Chirp spectrum

Also I want to add high frequency noise(MHz range) to my chirp signal (with frequency 270-330KHz) and then filter it out by using band pass filter. Can you suggest me how to add noise to any signal in labview?

Not sure if there is a quicker way but just use the Gaussian White Noise VI, FFT, zero the amplitude of everything outside of your target frequency range, inverse FFT, add to your target signal. When doing the FFT and IFFT pay make sure you keep the phase included.

Hi ConnerP!

I am attaching 2 vi's. Would you please run these and tell me what is wrong with them. I am testing a high frequency chirp(270k-330k). It's frequency spectrum before transmitting and after receiving. Although transmission part is working just fine. Something is wrong with receiving; data acquisition. And how to take frequency spectrum after receiving the signal back.

Also please tell me if there is any way I can export my labview file to Matlab.
