Design of IIR Filters by Impulse Response Optimisation
MetadataShow full item record
The contribution describes a program system to design digital IIR filters by optimisation of impulse response. Besides briefly presenting the already published method, it emphasizes the necessity to regularize the problem by changing the requested impulse response into a causal one by reshuffling its values. The program enables to design the filters starting from either frequency or time domain response and also from a manually prescribed pole configuration which is particularly useful for teaching purposes.
