Abstract
A stereo separation circuit includes a pair of amplifiers and a pair of divider circuits. Each of the amplifiers is coupled to receive a stereo signal (e.g., a left stereo signal or a right stereo signal) and the output of the other amplifier through a portion of one of the divider circuits. The other portion of the divider circuit is coupled as feedback across an amplifier. A ratio between the feedback portion of the divider circuit and the other portion of the divider circuit provides a separation ratio. The greater the separation ratio, the greater the perceived audio separation of the stereo signals.
