A recursive matrix approach to spectral transformations for digital filters
Information Sciences and Systems, CISS 43rd Annual Conference
The problem of converting a digital prototype filter, Hp (z), to a filter with specified cutoff parameters involves computing a new filter, H (z), from the prototype filter. A new recursive matrix approach for the conversion is presented. This simpler and more direct method is used to convert digital lowpass-to-digital lowpass filters and digital lowpass-to-digital highpass filters.
