This project is about designing generalized MATLAB codes that perform discrete convolution and discrete-time Fourier transform (DTFT) to audio and voice signals. Signal-processing MATLAB functions like “conv”, “filter”, and “fir1” are used to manipulate the input voice signal with different filters and study the output spectrum.
This project is about using a simple Z-transform transfer function of a digital filter that filters out certain noise frequencies in an input signal using MATLAB.
Executed Jupyter notebooks and searchable reports for DSP Labs 1-7: sampling, LTI systems, Fourier analysis, frequency response, FIR, IIR, and audio filtering.
