Means for reducing signal components outside of the desired band in a compatible single sideband system

Claim 1

A TRANSMITTER FOR TRANSMITTING SINGLE-SIDEBAND SIGNALS COMPRISING A SOURCE OF INFORMATION SIGNALS, A SOURCE OF FIRST CARRIER WAVE OSCILLATIONS OF PREDETERMINED FREQUENCY, FIRST AMPLITUDE MODULATOR MEANS FOR AMPLITUDE MODULATING SAID FIRST OSCILLATIONS WITH SAID INFORMATION SIGNAL TO PRODUCE FIRST SINGLE-SIDEBAND SIGNALS, SECOND AMPLITUDE MODULATOR MEANS, FIRST CIRCUIT MEANS FOR APPLYING THE OUTPUT OF SAID FIRST MODULATOR MEANS TO SAID SECOND MODULATOR MEANS BY WAY OF FIRST AND SECOND PATHS, WHEREBY THE SIGNALS APPLIED TO SAID SECOND MODULATOR MEANS BY WAY OF SAID FIRST AND SECOND PATHS ARE MULTIPLIED IN SAID SECOND MODULATOR MEANS, MEANS FOR LIMITING THE OUTPUT OF SAID SECOND MODULATOR MEANS TO PRODUCE SECOND CARRIER WAVE OSCILLATIONS, OUTPUT MODULATOR MEANS, MEANS APPLYING SAID SECOND CARRIER WAVE OSCILLATIONS TO SAID OUTPUT MODULATOR MEANS, SECOND CIRCUIT MEANS FOR APPLYING SAID INFORMATION SIGNALS TO SAID OUTPUT MODULATOR MEANS, WHEREBY SAID SECOND OSCILLATIONS ARE MODULATED BY SAID INFORMATION SIGNALS, AND DYNAMIC CONTORL MEANS CONNECTED IN AT LEAST ONE OF SAID FIRST AND SECOND CIRCUITS, SAID DYNAMIC CONTROL MEANS COMPRISING MEANS FOR INCREASING THE RATIO BETWEEN THE MODULATION INDEX OF SIGNALS FED TO SAID LIMITING MEANS AND THE MODULATION VOLTAGE OF SAID OUTPUT MODULATOR MEANS WITH INCREASE IN THE AMPLITUDE OF SAID INFORMATION SIGNALS.
