A digital baseband (DBB) radio frequency (RF) receiver includes a digital
high pass filter compensation (HPFC) module used to suppress group delay
variation distortion caused by using low cost analog high pass filters
(HPFs) in the receiver. The digital HPFC module reduces a cutoff
frequency, established by the HPFs for the real and imaginary signal
component frequency domain responses by providing a first compensation
signal having a first predetermined value (K.sub.1). The digital HPFC
module adjusts the gain of the high pass response of the real and
imaginary signal component frequency domains by providing a second
compensation signal having a second predetermined value (K.sub.2).
