Claim 8:
9. The apparatus of claim 8 further comprising:
the digital MRA and offset compensation circuit configured to perform the second MRA compensation and the second DC offset compensation, further including:
add the DC offset value to the digital sample sequence via a first adder to produce an offset-compensated signal;
apply the offset-compensated signal to a squaring operation to produce a squared offset-compensated signal;
multiply the squared offset-compensated signal and the second MRA compensation value via a multiplier to produce an MRA compensated signal;
combine the offset-compensated signal and the MRA compensated signal via a second adder to produce a digitally compensated signal; and
provide the digitally compensated signal to the digital backend circuit.
