ABSTRACT:
The subject sampling filter employs fractional period displacement of samples to force additional nulls in the filter characteristic response. This sampling method and cascading antialiasing filters provides a filter structure which minimizes the complexity of the circuit yet which provides great flexibility to implement a desired filter characteristic.
