Abstract
An apparatus for judging if a co-channel interference exists in a digital TV receiver is disclosed. The TV receiver includes a comb filter for removing NTSC interference of input data, and a selector for selectively outputting data which passed through the comb filter or data which did not pass through the comb filter according to a selection signal. The apparatus includes a gain controller for controlling the gain of noise which did not pass through the comb filter to change the point of time for turning on/off the comb filter, thereby optimizing the performance of the TV receiver for the channel noise and NTSC co-channel interference.
