The HSP43220™ from HARRIS Corp. is a two-stage linear-phase FIR filter for decimation. The first stage, which is shown in Figure. 4.66, is a high-order decimation filter that allows decimation by factors up to 1024. The maximum input sample frequency is 30 MHz. Input data word length is 16 bits using two’s-complement representation.

Audio application, Decimation filters, half-band filters 2. FILTER ARCHITECTURE 1. INTRODUCTION Decimation filters should be computationally efficient since a very high over-sampling ratio is used for the delta-sigma In wireless and audio applications, over-sampling analog- modulator.

Decimation Filters have a better understanding how decimation filters operate, we created an example. Note that in a delta-sigma converter, the decimation filter is placed after the modulator. Assume a first-order delta-sigma modulator is used to generate a bit stream at the modulator’s output (Figure 1).

2.1 Basics 2.1.1 What are “decimation” and “downsampling”? Loosely speaking, “decimation” is the process of reducing the sampling rate. In practice, this usually implies lowpass-filtering a signal, then throwing away some of its samples. “Downsampling” is a more specific term …
