In Multisim Fourier series

• Problem addition thanks to a For loop

  I have the following diagram, set up to make the amount of a fourier series, given the tables containing the coefficients.  The coefficients are determined externally, loaded into a table, then "n" is changed for each iteration and the results, summed up with any other "n" 1 to 5 now.

  Everything looks good, but the loop isn't adding up the results.  Can someone point me in the right direction to solve this problem?  All this is in a case at the moment structure so that I can run the vi, the load factors, and then run the loop for.

  Thus, the feedback node must be avoided as much as possible.

  Sometimes I disagree with this statement (and feeling).  I don't 'avoid' a lot of things in LV, not same inhabitants.  I understand the options and apply to one that works at any given time.  It happens that the inhabitants are not the best option in almost all cases.  Comment nodes are much more useful than the locals, and you lack much avoiding them.  They must be respected, understood, but not to fear.  In the case of ease of use, they can often be traded for a quarter of the common register and LV will do for you.  Comment nodes have other important features which make them useful in some cases.  The ability to exist without the loop, so no more single iteration while loops just to hold a registry change is a good example.  Initialization with a table is another.  More help and some topics of the forum for a discussion.

  In this case, the fundamental flaw is that the FN must be inside the loop.  Fixing ben64 example shows how it's done.

  

  No difference between SR and FN in this case, but no reason to avoid it.  In fact, in most of the new code I write I tend to favour the FN since they often shorten wiring and everything I can do with an SR can I do with a FN but not vice versa.

• stop Fourier if she has too long

  How can I stop the Fourier transform vi if the user accidentally up in too much data and too long, we need to finish?

  Guess I should use the asynchronous call of application control palette, vi of the and block other calls with a semaphore until termination.

  As much, I can see, the FT vi is called in a separate default thread. But I can't find any vi called "stop this thread instantly even though he has not yet finished" or something similar.

  If possible, I don't want to stop the vi together on the time-out period (which would be easy with parallel while loops), but only the vi FT.

  Better yet, I want to give the user the choice if/when to stop the Fourier transform.

  What is the size of the array to access the fft? (Note that if there is a single NaN in the data, it might take hundreds of times longer, so watch out for this.)

  Is the 1 d or 2D FFT? If this a 2D FFT, you could replace it with a series so 1 d FFT and seek termination of the terms after each slice, for example.

• Multisim 12 - by clicking on the button "stop the simulation", does not seem to turn off the circuit

  Greetings.

  I recently installed 12 Multisim and have not changed the basic operational parameters, I know...

  Shortly after installation, the application is an update.

  Your help is apprecaited to understand what is happening...

  Steps to recreate:

  1. start multisim.

  2. open a very basic circuit that includes a battery 10V with the ground, a lamp, a voltmeter between the lamp and an ammeter in series.

  3. use 'switch' at the top right of the appliation multisim window to run the simulation.

  4 lamp shows a 'enlightenment' and voltmeter indicates 10V and ammeter indicates .1a circuit.

  5. use the switch to stop the simulation.

  6. no change in the circuit or lighting of the lamp measures.

  7. same results if the simulation starts the arrow and the red square are used to start and stop.

  If I close it and reopen it circuit, the circuit begins in the OFF state, but will not OFF If when you select stop simulation.

  This is the case with several circuits, those provided by the College and the other that I created based on the same design.

  Multisim restarting has no effect to correct this observation.

  It doesn't seem normal that when the simulation running, values or apparent lamp lighting does not change.  The simulation doesn't have to go back to the start state (OFF) when I stop the simulation?

  I captured the homerun status after stopping the simulation.

  Thanks in advance for your help.

  Hi zanzarista,

  Multisim retains the values for everything in the circuit when the simulation is stopped. Which means that you are able to view the values on your instruments (such as multimeters) even after the termination of the simulation. When you start a simulation once again, starts all over again and that's why you see a 0 momentarily.

  It is the way in which the software is intended to work.

  I hope this works.

• Execution of Multisim with Labview

  Hey,.

  I'm trying to convert a series of laboratories studying for a class of dynamic systems run on a newer, better set up.  Previously, the laboratory, I'm working on that took input from a sensor, fed entry through an analog circuit that feeds the output of this circuit a Labview VI.  My question is, which is possible by using a Multisim simulation instead of a physical circuit?  I found volumes about Labview screws running in Multisim, but nothing about a taking a Multisim circuit inlet VI.  If this is possible, what configuration do you suggest?

  
  

• Problem with pole-zero analysis using multisim

  Problem with pole-zero analysis using multisim

  Party a pole / zero analysis is linearizing circuit using an operational RODC analysis, in which a driver acts as a short circuit. The problem is that in your circuit, the inductor in parallel with a source of internal tension unit.

  Use a small resistor (1mOhm will do in your case) in series with the generator output functions to break the loop short-circuit.

• Apple Watch series 2 measure gain altitude or altitude?

  Hello

  I'm confused, the 2 series watch is not supposed to have a barometer, but today after I watched a training session (open air cycle) in the activity of application on my iPhone I saw 'elevation' win (622 m) and it was there (compared to a parallel measure with a Garmin 920XT). I registered the workout on the watch, but had my iPhone (6s) in my pocket. So the series 2 Watch measures altitude/elevation or he draws the data from my iPhone... I'll experiment more, without taking my iPhone along next time.

  During this time, is that what someone did similar comments?

  And of course, I would be grateful for any help on how to export training sessions (write to GPX etc.).

  Thanks and best wishes

  Yes, the watch/app will draw altimetry from your phone when it is within range.

• Apple Watch series 2 protective case

  Hello

  Has anyone found a real Apple Watch S2 case? You are looking for a minimalist design, to display the watch itself without inhibiting its look, then perhaps a clear case (case bumper or other) will do.

  All cases online specify that they are cases Apple Watch S2, but look further into what they are not, as many of them do not account for the new air port (hole on one side, not two) and are also not the right depth, and cutting a port speakers are designed for S1 S2 not.

  You will need to protect my camera, I do use it in the gym a fair bit and worry about the damage.

  Thanks guys and girls!

  Hi RudeBwoy!

  I had the same problem. As far as I can see, case or bumper for the AW 2 series do not exist. I talked to Spigen, catalyst and a couple of others and any sites third 3rd say... manufacturers confirm that their AW products are NOT compatible with series 2 Watch, and that they are working on it!

  All thoughts of good screen protectors? !! They would be compatible? Some protection is better than nothing!

  Let me know if you hear anything!

  Thank you

• before you go swim with my series 2. I need to activate the waterlock feature? or is it automatic? and just to unlock after swimming

  Hello

  Swimming workouts

  Begin a swim practice in the application of the workout on Apple Watch series 2 models automatically activates the lock of the water, which locks the screen to avoid accidental interactions during your workout.

  To complete your workout and to evacuate all the water:

  • Press the digital Crown and side button at the same time (which makes a break from the workout).
  • Turn the digital Crown, which opens the screen and erases all the water inside of the watch (it can make a sound).
  • Forehand and press end.

  Other swimming

  If you plan to get your Apple Watch series 2 wet in other circumstances that when training of swimming - as to the course of General wear in a pool - you can manually lock the screen first and then drain the water from the speaker subsequently:

  • Slide up from the bottom of the face of the watch to open Control Center > tap water from lock to lock the screen.
  • When you're done: turn the digital Crown to unlock the screen and drained the water from the speaker.
  • The lock can also be unexpected water activated and unlocked immediately after exposure to the water.

  After bathing, make sure to clean your Apple Watch series 2 by rinsing them with hot water from the tap. Watch and the band should be dried with a non abrasive and non fluffy cloth.

  Strips of leather and stainless steel (Milanese Loop and Bracelet links) are not water resistant, so should not be worn when swimming.

• Will the 2 series watch track swim properly if using a kick Board (without using arms to swim)?

  I have a friend that is considering a 2 Apple Watch series.  It will systematically use a Board during training for her swim meets.  The new Apple Watch will follow distance and calories correctly even if it does not use his arms while swimming with a surfboard?

  I used my series 2 during my bath today for the first time. It does a great job of tracking my laps... freestyle, free with paddles and open palms. But he is not one of my kicks. I threw it only Dolphin on my back (without arms). I swam more than 250 kick 3500yds, it does not register at all. Next time I might try on my stomach, but without a Board of Directors and use my arms a little to breathe.  Overall I was impressed but.

• Where is the application of friends for series 1
