Due Feb 23rd weProb 4.1 This problem demonstrates aliasing. Generate a 512 point waveform consisting of two sinusoids at 200 and 400 Hz. Assume a sampling frequency of 1 kHz. Also generate another waveform containing frequencies at 200 and 900 Hz. Take the Fourier Transform of both waveforms and plot the magnitude of the spectrum up to fs/2. Plot the 2 spectra superimposed, but in different colors to highlight the additional peak at 100 Hz due to aliasing. You can use the equation xesin(2 piirt+sin(2"pi12"), where f1 is 200 Hz for both signals and 12 is 400 for one waveform and 900 for the other waveform
