How do you design a filter?
One common method for designing FIR filters is the Parks-McClellan filter design algorithm, based on the Remez exchange algorithm.
Here the user specifies a desired frequency response, a weighting function for errors from this response, and a filter order N.What is a digital filter in design?
A digital filter is a mathematical algorithm implemented in hardware and/or software that operates on a digital input signal to produce a digital output signal for the purpose of achieving a filtering objective.
In signal processing, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal.
What are the steps in digital filter design?
Digital filter design involves four steps:
1.1) Determining specifications.2.
2) Finding a transfer function.3.
3) Choosing a realization structure.4.
4) Implementing the filter.
