Patent ID: 6859238

Claim:
In a demodulator suitable for converting television signals to video baseband signals and audio baseband signals including stereo signals representing a right channel signal value and a left channel signal value, a method of improving stereo separation of the stereo signals comprising: converting at least the audio baseband signals to corresponding digital signals; scaling the digital signals according to at least one coefficient having a series of different coefficient values; generating in response to the digital signals scaled according to the series of coefficient values a series of first digital signals corresponding to the right channel signal value; generating in response to the digital signals scaled according to the series of coefficient values a series of second digital signals corresponding to the left channel signal value; generating a series of separation signals representing the stereo separation represented by the series of first digital signals and the series of second digital signals; storing the separation signal representing the largest stereo separation as a preferred coefficient value; and scaling the digital signals according to the preferred coefficient value.
