(You might find it easier to work in frequency domain). (b) Implement your multiplexing algorithm in Matlab. You should design your filters as FIR lowpass filters based on a lowpass prototype filter. (c) To test your multiplexer design, assume that B=4kHz and 4 sinusoidal signals x i (t) are used as input each having a frequency less than 4kHz. In order to distinguish them, you should choose 4 different frequencies. Plot your input signals x i (t), the output signal y(t) and required intermediate signals using Matlab. Hint: Use the IEEE paper which is posted on the web site to develop your algorithm....
