Solve this please

A DSP design engineer used the following Matlab code to design FIR filter. fs=8000; f=[00.15 0.25 0.4 0.51]; % edge frequencies m=[0 0 1 1 0 0]; % ideal magnitude w=[39 10 39];% error weight factors format long b= remez (25, f, m, w)% Parks-McClellen algorithm and Remez exchange Review the above MATLAB program, answer the following question: Which of the following method does he/she use? Mark one of them. a) Optimal design method b) Fourier transform method c) Fourier transform using a window method Determine the number of taps = Determine the type of the filter. Mark one of the following a) lowpass b) bandpass c) highpass d) bandstop

Explanation / Answer

1. Optimal design method

2. 25+1

3.Bandpass filter ( shown from its Magnitude vs Frequency graph)
