Application note

Filters using the ST10 DSP library

Introduction
The ST10F2xx family provides a 16-bit multiply and accumulate unit (MAC) allowing control-oriented
signal processing and filtering widely used in digital applications.
An ST10 DSP software library, developed by STMicroelectronics, contains a set of basic arithmetic
operations such as multiplication as well as two main filter functions, FIR (finite impulse response) and IIR
(infinite impulse response), mainly used in digital signal processing.
The first chapter of this application note describes a theoretical dig
