Amplitude compensated pulse duration modulator
Abstract
Abstract AN AMPLITUDE COMPENSATED PULSE DURATION MODULATOR INCLUDING A PULSE DURATION MODULATION SYSTEM HAVING MEANS FOR COMPENSATING FOR THE EFFECT OF STRAY CAPACITANCE AT THE AMPLIFICATION STAGES BY MEANS OF AMPLITUDE MODULATING THE PULSE DURATION MODULATED SIGNAL. THE AMPLITUDE MODULATED PULSE MODULATED SIGNAL IS APPLIED TO THE GRID OF AN AMPLIFIER MEANS AND THE OPERATION OF THE AMPLIFIER MEANS IS ESTABLISHED SUCH THAT THE AMPLIFIER IS DRIVEN INTO SATURATION FOR ALL PULSES EXCEPT COMPARATIVELY SMALLER AREA PULSES OF THE PULSE TRAIN. ACCORDINGLY, THE PULSE TRAIN RETAINS A MODULATION EFFECT ONLY FOR THE SMALLER AREA PULSES THEREBY ALLOWING THE AMPLITUDE MODULATION TO COMPENSATE FOR THE REACTANCE EFFECT OF THE AMPLIFIER ON THE SMALLER PULSES ONLY.
