IIR Tool

IIR Tool
In the digital domain, analogue signals can be easily manipulated without requiring different hardware for each operation (as is necessary for analogue circuits).Other important advantages are that no noise is added during the operation (provided it is programmed correctly) and that mathematical algorithms are easier to implement.Unfortunately, the design of a digital filter is not that straightforward. There are several methods for implementing a digital filter. A relatively efficient filter implementation is the IIR (Infinite Impulse Response) type. The filter is mathematically represented as: ...
