Abstract
An apparatus and a method of automatically compensating a difference between audio signals of an analog broadcast and a digital broadcast depending on a difference of a modulation degree of an analog audio signal and a digital audio signal. The apparatus includes an analog demodulating unit to demodulate an analog audio signal of a tuned analog broadcast channel, a digital demodulating unit to demodulate a digital audio signal of a tuned digital broadcast channel, a switching unit to receive the audio signals from the analog demodulating unit and the digital demodulating unit and to selectively output the received audio signals, an audio amplifying unit to amplify the audio signals output from the switching unit at a predetermined amplification degree, and a central processing unit to control the switching unit to output the audio signal of the digital demodulating unit and to control an amplification degree of the audio amplifying unit as the digital broadcast channel is tuned by a user, to allow the output audio signal of the digital broadcast channel to have the same magnitude as when the corresponding analog broadcast channel is tuned.
