Synthesis of multibandpass numerical filters
K. Sridharan, V. Sinha · IEEE Transactions on Audio and Electroacoustics · 1970
The problem of low-pass to multibandpass transformation of numerical filters is considered. Properties of frequency transformations are studied and, based on these, a general design procedure is outlined which may be used for obtaining filters with any number of passbands. The procedure is illustrated by means of a ten passband example. A canonic form for realizing bandpass filters is also discussed.
