Hi everyone.
I am currently working on SFCW signals. Currently I want generate the SFCW signal and plot the power spectrum of it.
For the testing purpose, I use the following values:
Start frequency: 100
Stop frequency: 200
Step size: 2
Sampling frequency: 1000
No of samples: 100
Attached is the vi and the result.
My question is, instead of plotting power spectrum for every stepped frequency, why only one frequency appeared in the graph.
Thank you in advance.
