To a certain … 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:

The musical passage is likely to sound artiﬁcial, because it is created from pure sinusoids. You can improve the quality of the sound by multiplying each pure tone signal by an envelope E(t) so that it would fade in and out. x(t) = E(t)cos(2ˇf 0t+ )
