Course Outline

Day 1 

SIMULINK for Signal Processing

This provides an introduction on how to develop signal processing algorithms for FPGA device using Simulink. The basics of using the Signal Processing Blockset in SIMULINK to analyze and design a signal processing system will be covered. The first part includes an introduction to signal processing with a concentration on representations of signals in MATLAB, signal analysis, and filter design, with FIR design. Multirate system is also discussed.
