For each of the following specifications, use built-in MATLAB functions to design two or more different filters and display their magnitude responses. Also state what their implementation costs are (number of additions and multiplications per sample). Assume a sampling rate of 1000 sps. - Band-pass filter with cutoff frequencies 50 and 150 Hz. - Band-reject filter with cutoff frequencies 50 and 150 Hz.
Using the windowing functions discussed in class, design a
low-pass FIR filter with a cutoff frequency of 2 kHz, a minimum
stop band attenuation of 40 dB, and a transition width of 200Hz.
The sampling frequency is 10kHz.

[MATLAB Scriptfile task]
Design N-band tone vocoder with a given figure (below) in MATLAB
implementing the given script file(bands_cutoff). This program
should be able to process any sound(.wav) file. Then, graph the
band-passed signals and amplitude envelopes extracted(after
rectification and low-pass filtering) and waveforms of the original
sound and vocoded sound. Additionally, using the output of the
script file, make spectrograms of the original sound and the
synthesized sound.
