Description: 1. X = 0.5* sin (2* PI* 15* t)+ 2* sin (2* PI* 40* t).Sampling frequency fs = 100 hz, respectively to draw N = 128, 1024 point amplitude-frequency figure.
2. X = 0.5* sin (2* PI* 15* t)+ 2* sin (2* PI* 40* t), the fs = 100 hz, drawing:
(1) N = 32, NFFT = 32
(2) N = 32, NFFT = 128
(3) N = 136, NFFT = 128
(4) N = 136, NFFT = 512.
