Sample both signals at 44100 Hz (CD quality). Visualize the obtained spectrum and listen to the obtained signal. Notes: You will notice in the spectrum an impulse @600 Hz : alias of the frequency 43500 Hz at (44100 - 43500 = 600). We should precede the sampling process by an anti-aliasing filter in order to prevent the aliasing effect. 11/3/20 Prot. Hesham Torba Del Carmications

If the sampled signal is passed through an ideal low pass filter with a cut off frequency of 400 Hz, what frequency components will appear in the filter output?
