How to do frequency scaling in Frequency spectrum?. Learn more about frequency spectrum, frequency scaling, principle communication, signal and system MATLAB
Store the signal and its time information in a MATLAB® timetable. Get Fs = 1000; t = (0:1/Fs:0.296)'; x = cos(2*pi*t*200)+0.1*randn(size(t)); xTable = timetable(seconds(t),x); Compute the power spectrum of the signal. Express the spectrum in decibels and plot it. ...
