Title:
HARMONIC GENERATOR AND PRE-AMP
Document Type and Number:
WIPO Patent Application WO2005020432
Kind Code:
A3
Abstract:
A Harmonic Generator (12) for audio applications and a Pre-Amplifier circuit (14) are combined to form a Harmonic Generator and Pre-Amplifier circuit. The Harmonic Generator (12) is formed from a Buffer Circuit (16) responsive to an input program signal (18) for buffering the input program signal (18) and for providing a buffered input program signal. A Modulator Circuit (22) is coupled to receive the buffered input program signal and generates harmonics in response to changes in amplitude of the program input signal (18) to provide a modulated input program signal. A Summing Circuit (28) adds the buffered input program signal and the modulated input program signal to provide a composite modulated input program signal. The Pre-Amplifier (14) is coupled to receive the composite modulated input program signal and process the signal in three audio frequency bands.
