Amplified signalling signal harmonic oscillation compensation circuit for ADSL interference reduction calculates amplitudes and phases for compensation signal applied at input

摘要

An amplified (2031) signalling signal harmonic oscillation compensation circuit has an adaptive unit (40) calculating the the amplitudes and phases for a compensation signal (KS) and signal generator (2013) generating it for addition to the Signalling signal (SS) at the amplifier input. INDEPENDENT CLAIM is included for a harmonic compensation procedure using the circuit.
