Television receivers receieve a television signal and downconvert the
television signal to generate a complex baseband signal. The complex baseband signal
is differeniated and then integrated to reduce a direct current (DC) offset in
the complex baseband signal. The television receiever may include a periodic known
information field. The known information field is correlated with the integrated
signal to determine a residual offset therein that is associated with a constant
used in integrating the differentiated complex baseband signal. The residual offset
is substracted from this constant when integrating the differeniated complex baseband signal.
