WebGiven t, you can create a sample signal y consisting of two sinusoids, one at 50 Hz and one at 120 Hz with twice the amplitude. y = sin (2*pi*50*t) + 2*sin (2*pi*120*t); The new variable y, formed from vector t, is also 1001 elements long. You can add normally distributed white noise to the signal and plot the first 50 points:

WebMay 21, 2012 · You can make a sine wave out of any wave of a fixed frequency, as long as you have a filter that passes the fundamental frequency, but blocks 2x frequency (as you would be leaving only one harmonic in place).
