Abstract
A transmitter for single-sideband broadcast transmission which operates in accordance with the principle of combined amplitude and phase modulation generating a single-sideband signal and splitting this signal into an amplitude-modulated component applied to an amplitude-modulated path and a phase-modulated component applied to a phase-modulated path. An amplitude-modulation path is a D.C. voltage-coupled signal path from an envelope-curve detector to a radio-frequency amplifier (2). This results in direct floating-carrier modulation in a radio frequency amplifier in which the amplitude-modulated and phase-modulated components are amplified and recombined.
