Electric pulse wave clipping circuitry

Abstract

Abstract WITHIN LIMITS EACH PULSE OF AN INPUT ELECTRIC PULSE WAVE SETS THE CLIPPING LEVEL OF THE CLIPPING CIRCUITRY TO WHICH THAT PULSE IS APPLIED. A SQUARED OUTPUT ELECTRIC PULSE WAVE IS DEVELOPED IN AN OVERDRIVEN DIFFERENTIAL AMPLIFIER CIRCUIT. THE INPUT CIRCUITRY OF THIS DIFFERENTIAL AMPLIFIER OPERATES TO CLIP THE INPUT ELECTRIC PULSE WAVE APPLIED TO ONE INPUT TERMINAL IN ACCORDANCE WITH CLIPPING LEVEL VOLTAGES APPLIED TO THE OTHER INPUT TERMINAL. THE CLIPPING LEVEL VOLTAGE IS DERIVED FROM THE INPUT ELECTRIC PULSE WAVE IN A NETWORK HAVING POSITIVE AND NEGATIVE PEAK DETECTING CIRCUITS COUPLED TO A MIXING CIRCUIT. THE OUTPUT OF THE MIXING CIRCUIT IS A DYNAMIC CLIPPING LEVEL VOLTAGE WHICH IS APPLIED TO THE DIFFERENTIAL AMPLIFIER. THE INPUT ELECTRIC PULSE WAVE IS DELAYED BEFORE APPLICATION TO THE DIFFERENTIAL AMPLIFIER CIRCUIT TO PROVIDE TIME FOR THE GENERATION OF THE CLIPPING VOLTAGE. CROSS COUPLING BETWEEN THE PEAK DETECTING CIRCUITS EFFECTS RESETTING OF EACH OTHER AFTER EACH PULSE IS DETECTED IN READINESS FOR THE DEVELOPMENT OF A NEW CLIPPING LEVEL VOLTAGE FOR THE SUCCEEDING INPUT PULSE. A LONG TIME CONSTANT NEGATIVE PEAK DETECTING CIRCUIT AND A FURTHER MIXING CIRCUIT ARE INCORPORTED IN AN EXTENDEND EMBODIMENT FOR APPLYING A VOLTAGE TO THE BASIC NEGATIVE PEAK DETECTING CIRCUIT PREVENTING IT FROM RESTORING ABOVE A VOLTAGE DEVELOPED IN THE FURTHER MIXING CIRCUIT FROM THE LONG TIME CONSTANT AND THE POSITIVE PEAK DETECTING CIRCUIT. THUS, WAVES OF PULSES OF STEADILY ASCENDING AMPLITUDE ARE CLIPPED WITHOUT LOSS OF FIDELITY.
