###### Question:

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. Demonstrate the operation of the filter using audio file (.mp3 format) b. Plot magnitude and phase response of the filter using matlab program on a normalized scale. C. Plot the spectrum of voice signal before and after filtering, assume scale (-n to π) radians. d. Implement the filter on TMS processor and demonstrate your understanding of the filter implementation. e. Critically analyze the design specification. 1.
