A demodulator (18) which receives digital representations of a received signal converts those signals into analog signals (53) in a pair of multiplying analog-to-digital converters (MDACs) (21, 22) The analog signals are then combined in combiner (26) by subtracting the first analog signal from the second analog signal (54). The summed signal is normalized (55) in quantizer (27). The output from the quantizer (27) is accumulated (56) in an n-bit accumulator (28) as regulated by a clock input (Fclock). The output of the accumulator (28) is used as a programming input (57) to the MDACs (21, 22).
