5. In this exercise, we study the use of filters to recover the frequency components from a mixed signal. In the Filter Design & Analysis Tool, click “Export to Simulink Model” and “Realize Model” to export the Butterworth filter in 4a to the SIMULINK environment. a. In SIMULINK, create two discrete-time signals x1 [n] and xz[n] expressed by the following equations: Ts = (1/48000) sec x1 [n] = sin(21fınts) xz [n] = sin(21f2nts), fi = 3kHz f2 = 6kHz i. Feed the signal x1 [n] into the Butterworth low-pass filter and use a scope to capture the input and output waveforms for 5ms. Show the circuit block diagram with the signal paths connecting the source, the filter and the scope. Show the input and output waveforms captured by the scope. From the waveforms, measure the gain and the time delay after the output has stabilized. Compare the gain and delay in this simulation with the design values in in Q4a. (6 marks) ii. Repeat the same exercise for xz[n]. Show the input and output waveforms captured by the scope. Comment on the output waveform
