Abstract
A circuit for discriminating between received signals and a method therefor are provided. The circuit includes a detector for detecting a peak signal based on the degree of correlation between a received signal and a reference signal and a generator for generating a discrimination signal showing that the received signal is a high definition signal if the peak signal is detected in a predetermined period and showing that the received signal is a signal of an analog broadcasting method if the peak signal is not detected in the predetermined period. This can prevent the improper operation of a receiver by automatically determining whether the received signal according to a channel selection is a high definition digital signal or an analog broadcast signal.
