Pulse amplitude modulated to pulse position modulated converter

Claim 1

AN ELECTRICAL SIGNAL TRANSLATING SYSTEM COMPRISING A SOURCE OF AMPLITUDE MODULATED PULSE SIGNALS IN WHICH THE PULSES OF MINIMUM AMPLITUDE ARE AT LEAST EQUAL TO A GIVEN AMPLITUDE, A SEMICONDUCTOR DEVICE INCLUDING A SEMICONDUCTING PORTION AND AN INPUT ELECTRODE, AN OUTPUT ELECTRODE AND AT LEAST ONE OTHER ELECTRODE IN CONTACT WITH SAID PORTION, CIRCUIT MEANS INTERCONNECTING SAID ELECTRODES INCLUDING MEANS TO BIAS SAID DEVICE TO ESTABLISH AN INPUT SATURATION LEVEL THEREFOR EQUAL TO SAID GIVEN AMPLITUDE, A FIRST RESISTOR AND A SECOND RESISTOR IN SERIAL ORDER TO COUPLE SAID INPUT ELECTRODE TO A REFERENCE POTENTIAL, MEANS TO COUPLE THE SIGNALS OF SAID SOURCE TO THE JUNCTION OF SAID FIRST AND SECOND RESISTORS, AND MEANS COUPLED TO SAID OUTPUT ELECTRODE TO REMOVE FROM SAID SEMICONDUCTOR DEVICE PULSE SIGNALS HAVING A DURATION VARYING IN PROPORTION TO THE AMPLITUDE VARIATION OF THE SIGNALS OF SAID SOURCE ABOVE SAID GIVEN AMPLITUDE.
