DSP-Based FIR Filter Design and Circular Buffer Implementation

Article Preview

Abstract:

The digital filter technology includes two aspects, which are the filter design process and filter realization. The article expounded the basic structure of FIR filter, with examples on the use Matlab to determine the FIR filter coefficient, analysis of the cycle of the buffer zone algorithm Principle, based on the algorithm, combination of filters designed to achieve the input of mixed-signal FIR digital filter. In the end, the filter is given before and after the input and output signal waveform simulation.
