Bandwidth compression utilizing magnitude and phase coded signals representative of the input signal

Claim 1

A BANDWIDTH COMPRESSION SYSTEM THAT COMPRISES A TRANSMITTER TERMINAL INCLUDING A SOURCE OF AN INCOMING SPEECH SIGNAL, AND A PLURALITY OF ANALYZERS WITH INPUT TERMINALS CONNECTED IN PARALLEL TO SAID SOURCE FOR DERIVING FROM SAID SPEECH SIGNAL A CORRESPONDING PLURALITY OF PAIRS OF MAGNITUDE AND PHASE ANGLE CONTROL SIGNALS BY EVALUATING THE SHORT-TIME AMPLITUDE SPECTRUM AND SHORT-TIME PHASE SPECTRUM OF SAID SPEECH SIGNAL AT A CORRESPONDING PLURALITY OF PRESET FREQUENCIES THAT SPAN THE FREQUENCY BAND OF SAID SPEECH SIGNAL AT A CORRESPONDMEANS FOR TRANSMITTING EACH PAIR OF MAGNITUDE AND PHASE ANGLE CONTROL SIGNALS TO A RECEIVER STATION, AND AT SAID RECEIVER STATION, A PLURALITY OF SYNTHESIZERS HAVING OUTPUT TERMINALS CONNECTED TO AN ADDING MEANS, EACH SYNTHESIZER BEING SUPPLIED WITH ONE OF SAID PAIRS OF MAGNITUDE AND PHASE ANGLE CONTROL SIGNALS, WHEREIN EACH OF SAID SYNTHESIZERS GENERATES AT ITS OUTPUT TERMINAL A COSINE WAVE HAVING THE SAME PRESET FREQUENCY AS THE CORRESPONDING ONE OF SAID ANALYZERS AND HAVING MAGNITUDE AND PHASE ANGLE RESPECTIVELY SPECIFIED BY SAID PAIR OF MAGNITUDE AND PHASE ANGLE CONTROL SIGNALS, AND WHEREIN SAID ADDING MEANS COMBINES SAID COSINE WAVE GENERATED BY EACH OF SAID SYNTHESIZERS TO FORM A REPLICA OF SAID INCOMING SPEECH SIGNAL.
