1. An analog television signal receiver, comprising: a receiver configured to receive an analog television signal; and an adaptive filter device, including a finite impulse response (FIR) filter which is based on filter coefficients b k , the FIR filter configured to determine the filter coefficients, based on a predetermined iterative adaptation algorithm for determining filter coefficients of an adaptive filter, wherein, in at least one iteration step of said predetermined iterative adaptation algorithm performed by the FIR filter, a sum value is determined, wherein at least one summand of said sum value depends on at least one of said filter coefficients, and, if said sum value is above a predetermined threshold, the filter coefficients are modified, wherein the adaptive filter device is an equalizer configured to remove at least one multi-path echo of the received analog television signal.
