Signals and Systems

This repository is about Signal and Systems course projects at Amirkabir University of Technology Spring 2022.

1)

  • Working with numpy, matplotlib

  • Learned impulse, unit step signals

  • Time shifting

2)

  • Implementing Convolution of two functions

  • Tested with numpy.convolve

3)

  • Fourier series for continuous signals

  • Computing coeffecients of Fourier series

  • Rebuilding the input signals using computed coeffecients

4)

  • Fourier transform of continuous signals

5)

  • Sampling a signal using sampling rate

Bonus project

  • Noise detection (women or men)

  • Fourier transofrm for spectral analysis

  • Power spectrum

  • Noise elimination

  • AWGN algorithm

  • Spectral Subtraction
