Abstract
A method for processing an analog television signal. A reference signal based on a field synchronizing signal of the analog television signal and equalizing the analog television signal based on the reference signal are determined. The reference signal is determined by calculating a difference between a first part of the field synchronizing signal and a second part of the field synchronizing signal, wherein the first and second parts are selected such that the reference signal is non-zero.
