Finite Impulse Response(FIR) filters are one of the two main type of filters available for signal processing. As the name suggests the output of a FIR filter is finite and it settles down to zero after some time. A FIR filter output can be defined by the following equation: N y[n] = [bx[n -i] =0 Here, y(n) is the filter output, x(n) is the filter input signal and b; are the filter coefficients. N is the filter order. Write a VHDL code to implement a simple 4-tap FIR filter. Include in your code a small test bench code and submit the simulation waveforms.
