Digital Signal Processing
Abstract
This chapter provides a practical introduction to digital signal processing (DSP), particularly the frequency representation of sampled signals, the fast Fourier transform (FFT), frequency response of filters, and finite impulse response (FIR) and infinite impulse response (IIR) filters for tasks such as low-pass filtering, high-pass filtering, bandpass filtering, and bandstop filtering. Concepts are explained with examples in MATLAB, followed by sample code implementing the FFT and FIR filters with the DSP library provided with the PIC32.
