409 Plotting and finding the magnitude of a wav file in MATLAB The question was; Load the file sound1.wav (You would use MATLAB command ‘wavread’ to loadthis file. Use MATLAB help to learn the usage of ‘wavread’). This file contains a portion of speech

409 Sampling of a Sinusoidal Signal and finding the DTFT The question was : Write a MATLAB function, x = SinSamples(A, w, θ, d, ws), that generates a discrete-time sinusoidal signal x[n] obtained by sampling x(t), (Assume that x(t) is a
