Abstract
A system of downconverting an intermediate frequency (IF) phase or frequency modulated signal to a digital baseband includes an N bit shift register circuit that receives a binary input as a 1-bit input sample data stream of an IF signal. A decimation circuit includes a memory and receives data from the N bit shift register circuit and stores N 1-bit binary samples as address bits and performs decimation, downconversion and filtering by accessing memory values at a predetermined rate.
