Signals-Applications with MATLAB

1) Echo Generation-Removal to an input audio signal

Echo Generation using Convolution of an Impulse Response & the Input signal

Echo Removal using deconvolution with FFT & IFFT

2) Image Compression and Decompression

Image Compression by processing each of its color components (red,green,blue) in blocks of 8X8 pixels then compress each block using 2D Discrete Cosine Transform (2D DCT)

Image Decompression by applying inverse 2D DCT to each block

3) Audio Steganography
