estimating resonant frequency by sweeping the frequency from 100 Hz to 500 Hz

[engkhalid]

Dear NabilahF, 

thank you  so much for the help. However, the code is working now  probably, but I have question about the main function of Trigger.vi in the code that you posted. How does it work? I have tried to read the manual to understand the main function of the trigger. Is this for detecting the signal from the input channel and generate signal as fast as possible?

Thank you so much for the help. However, the rms value of the sinewave is equal to (peak*0.7). Am I right?

No, it is about 0,707 and equal 1/sqrt(2)......
