Digital-Signal-Processing Filters (DSP)
By utilizing DSP’s capable of sequencing and reproducing hundreds to thousands of discrete elements, design models can simulate large hardware structures at relatively low cost. DSP techniques can perform functions such as Fast-Fourier Transforms (FFT), delay equalization, programmable gain, modulation, encoding/decoding, and filtering.

Filters, Delays, Modulations and Demodulations
A set of basic signal processing building blocks is presented and the implementation issues, that are relevant to musical applications, are underlined. in this text a filter classification is first outlined then implementation schemes for analog and digital lowpass-filters, within the canonical and the state-variable structure, are given. As well as higher order filters according to the Butterworth design are suggested, delay-based effects...

Introduction to Digital Filters
From introductory course in digital audio signal processing, which I have given at the Center for Computer Research in Music and Acoustics (CCRMA) since 1984. The course was created primarily as a first course in digital signal processing for entering Music Ph.D. students in the Computer Based Music Theory and Acoustics program. This book will emphasize audio and music applications . . .

Introduction to DSP - IIR Filters
This is the fifth module of the BORES Signal Processing DSP course - Introduction to DSP. It covers the following subjects: * IIR filter equations and frequency response * the z transform * the meaning of z * poles and zeroes * IIR filter design by impulse invariance * IIR filter design by the bilinear transform * direct form I and II filters * quantisation in IIR filters * IIR filter implementation structures
