error: the number of sample must be >; 0 Please help.
Dear genius.
I tried the same mistake in this forum, but I do not understand how I can solve my problem.
I'm just a beginner in LV, so I need your help. I made AM modulation and demodulation vi.
When I used 'fake signal' as signal message, noting happened.
but, I changed the signal simulated as 'acquire sound' and adds a waveform to play after that, there is problem.
in fact, I don't understand on the sampling frequency of number or a sampler.
How can I solve my problem?
and you know some site use digital communication with usrp and labview to try?
Please let me know your idea.
Thank you very much.
It seems that your alignment of waveform leave you with empty waveforms. You could just get rid of it. Just make sure that the number of samples generated in your carrier is identical to the one generated by your acquisition of the sound wave.

samples per channel and the number of samples per channel
in my DAQ mode samples finished program, there are two screws: timing and read.vi DAQmx DAQmx.
I have to set the parameter to "samples per channel" DAQmx timing.vi and 'number of samples per channel' on DAQmx read.vi... Is there a relationship between these two?
My laser runs at 1 K Hz. I want to go to the wavelength, wait for a number of shooting lasers, read the data and move on to the next page...
Thank you

In your case, the VI will acquire the lesser of either:
The "samples per channel" that you have defined on the timing DAQmx VI
-OR-
The number of iterations of your for loop (N) times the 'number of samples per channel"that you have defined on the DAQmx read VI
The "samples per Channel" VI DAQmx of timing for a finite acquisition dictates how many samples the DAQ hardware should acquire in it's onboard buffer before indicating that the acquisition is complete. "The number of samples per Channel" on the read DAQmx VI dictates how many samples the DAQmx driver must return buffer on board the aircraft to your application.
Let's say the "samples per channel" on the calendar DAQmx VI is set to 50. Thus, the card will acquire 50 samples and place them in the edge of the buffer, then stops. Suppose we have the 'number of samples per Channel"on the DAQmx reading VI the value 3 and what we call the VI in a loop For which runs 10 times. Thus, every time the DAQmx lu VI is called, it will wait until there are at least 3 samples in the buffer, and then return these three. We call the VI a total of 10 times, then we will answer 30 total samples. Thus, the last 20 samples acquired the card remains in the buffer and are destroyed when the task is disabled.
Now let's say that we increase the "number of samples per Channel" on our DAQmx Read VI at 10. VI Read will wait until 10 or more samples are in the buffer, and then return these 10. Thus, we will be back all 50 samples map acquired by the 5th iteration of the loop For. The 6th time we call him VI DAQmx Read it expires, because there will never be another 10 samples in the buffer, and the VI returns a warning.
This clarifies things?
The purpose of this behavior is to allow you to both set the total number of samples that the DAQ hardware will acquire and also control how much of these samples is returned whenever you call the DAQmx Read VI.
Kind regards

Units of the number of samples and rates for the DAQ Assistant units
Hello
I use the DAQ assistant for analog voltage of an input OR data acquisition card. What is the difference between the rate and the number of samples in the DAQ assistant and what are the units of the two?
Thank you.
The number of samples is how many discrete to measures. Rate (per second) is how fast to acquire the specified number of samples.
If number of samples is 100 and the rate is 1000 samples per second, then the acquisition would take 0.1 second (100 / 1000).

Enter the number of samples to simulate signal vi on front panel
Hello
I need to change the number of samples in the simulation of signals vi without manually going through properties. Is there a way to change this pattern-block or front panel?
Thanks in advance,
Ragmo
Yes. You can convert the Express VI to a normal VI by right clicking on it and selecting Open the front panel and then you can change this vI and change the # of samples of a control constant. You can also use the functions non - Express VI as a base generating function.

Who advised you to 'download... '. RegCure? Doing so could only worse issues! If you ever think that your registry database must be cleaned, repaired, boosted or optimized (it isn't), read http://aumha.net/viewtopic.php?t=28099 and draw your own conclusions.

Opatch error: the patch directory field must be a number.
Hello Sir,
I try to upgrade EBS 11i to R12, I come to this place of the document
· SQL> shutdown immediate;
· 27 apply additional 11.2.0.4 RDBMS patches
- For UNIX/Linux platforms, apply the patches of RDBMS
un) Patch 17468141 - opatch $ apply

- opatch $ apply
when I apply patch 17468141 ,
I had this error patch area directory must be a number, but I apply patches a lot before I do not had this error.
So please help me out in this matter.
Thank you
Ahmed.
Hello
If you want to upgrade the database 11g and the application of R12 in the same window of downtime, then do not follow the document ID 881505.1 and rather follow Doc ID 1058763.1.
If you want to upgrade to 11g and stay on 11i for awhile, you can then follow the document 881505.1. Patching must be performed while the application is down.
The examples CD is in 6 of the fix 13390677file. When you click Download, you will get a list of 7 files.
Download files 1,2 and 6 only.
Download OPatch step by step:
- Go to the download of patches
- Type the patch # 6880880
- Enter your platform (x 86 Linux, for example)
- Look for a patch with the description "hotfix version 11.2.0.3.10 of Oracle software OPatch publishes 11.2.0.x (April 2015).
- Download the patch
- Unzip the file into the 11.2.0.4 oracle home (unzip qo - p6880880_112000_LINUX.zip d $ORACLE_HOME)
- Check the version (version opatch)
Kind regards
