Signal a (t) is sampled for /V = 8000 samples at 40000 samples per second, resulting in signal a n]. MATLAB/Octave FX = fft (x) /N yields output of zeros except at MATLAB array indices { 201, 401, 601, 801, 7201, 7401, 7601, 7801}. (a) What is the duration of a n , in seconds? (b) a(t) consists of sinusoids at what specific frequencies, in Hz? (c) What is the period of a (t)?
