Chapter 5
Filters, Signal Generators, and Detectors
Abstract
Filters allow us to select and transform signals using linear operations. Detectors perform nonlinear operations to identify events on signals. Signal generators create useful signals. Filters can be built both as passive RLC filters and op amp-based active filters. Signals can be generated using analog or digital methods. Small analog circuits can be used to perform a range of useful detection functions. Design examples include a bass boost filter, arbitrary waveform generator, and headphone jack detector.
