can someone help me solve thisproblem by using matlab?
3. For this problem, we consider a signal made of the sum of three simultaneously present sinusoids s(t(2T fit) +sin(2Tf2t) sin(2T fst) 31311 at frequencies of 3 Hz, f27 Hz, and fs 11 Hz (a) Plot the signal as a function of time. Label the axis as amplitude and time in seconds. You can pick a range that covers several periods of the sinusoids (b) The signal is
