Please do it in MATLAB program
Record your voice signal in .mp3 format for 2 second duration and 8kHz sample frequency. Add a coloured noise with center frequency at 4KHz, assume the SNR =-5 dB. Design a FIR low pass filter (hamming) with cutoff frequency 3 KHz in Matlab and remove the noise, assume the sampling frequency same as the sampling frequency used for recording your voice and order of the filter as 15 a.

1. In the lab we analyzed filtering 60 Hz power-line noise from ECG signal using a digital (signal processing) filter. Now let's try to an analog (circuit) filter approach to remove the 60 Hz line-noise. Following is an active twin-T notch filter with transfer function: (1+m)((2joRC? +1 Z(a) 2R 2R Here m is the ratio of the two feedback 2C R resistance which determines the gain and...

[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.
