ABSTRACT:
There is disclosed an implementation of a digital intermediate frequency (IF) translator which accepts a digital converted IF input and performs a complex mix to produce an IF baseband output in I (in-phase) and Q (quadrature phase) format. The translator reduces the sampling rate and provides filtering to produce I and Q components which can be subsequently utilized to derive the information contained in the original analog input signal. The translator is implemented with a configuration which simplifies the complex mix required to produce I and Q components and accumulates the samples to provide boxcar filtering prior to providing the I and Q components as outputs at a reduced sampling rate.
