ABSTRACT:
The present invention may relate generally to a circuit for converting a first digital signal having a first sample rate to second digital signal having a second sample rate. The circuit may comprise a cascaded integration-comb filter and a fractional sample rate converter. The fractional sample rate converter may be configured to perform fractional sample rate conversion. A first of the cascaded integrator-comb filter and the fractional sample rate converter may be configured to receive the first signal having the first sample rate and to generate a third digital signal having a third sample rate different from the first and second sample rates. A second of the cascaded integrator-comb filter and the fractional sample rate converter may be configured to receive the third signal having the third sample rate and to generate the second signal having the second sample rate.
