Abstract
Transmission and reception of first and second information signals over a telephone local loop, simultaneous with voice communications over the same local loop, is possible if the phase and amplitude of said first and second signals are perfectly balanced. The inventive apparatus detects differences in phase and amplitude between said first and second signals, and generates digital control signals to reduce the phase and amplitude differences to zero. Adjustment of phase and amplitude is completely automatic and rapidly accomplished.
