Digital signal processing projects using Matlab cover major applications including biomedical imaging, seismology, image and video processing, consumer electronics, and military technologies. Some key DSP techniques explored include the discrete Fourier transform, Z-transform, signal separation and restoration, and ideal filter types. The Matlab wavelet toolbox supports projects involving discrete wavelet transforms, non-decimate wavelet transforms, data compression, image compression, and time series analysis.
