13.1. Channel Filter and Waveform Library

The DSP Builder advanced blockset Channel Filter and Waveform library contains several decimating and interpolating cascaded integrator comb (CIC), and finite impulse response (FIR) filters including single-rate, multirate, and fractional rate FIR filters.

Multirate filters are essential to the up and down conversion tasks that modern radio systems require. Cost effective solutions to many other DSP applications also use multirate filters to reduce the multiplier count.

FIR filter memory-mapped interfaces allow you to read and write coefficients directly, easing system integration.
