DIGITAL SIGNAL PROCESSING LABORATORY

This is a companion laboratory to EE-407-E (Digital Signal Processing - Theory). It includes experiments on representation of basic signals, convolution, correlation, sampling, and stability, designing of digital and analog filters. Emphasis is on Matlab based experiments. Practical demonstration of the theoretical concepts done in classrooms will enhance the understanding of the programming concepts in the lab.

The students are provided with a comprehensive Lab Manual, which is almost self explanatory. All the experiments are well documented with clear circuit diagrams, theory and programming concepts, so that the students are able to perform the experiments with ease and proper understanding.
