Abstract
1,245,958. Transistor circuits; pulse modulation Circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 19 Dec., 1968 [25 Jan., 1968], No. 60321/68. Headings H3T and H4L. In a pulse duration limiter circuit the input pulse is applied to one input of an AND gate and via a semi-conductor delay device and to another input, the output of the gate constituting the duration limited pulses. In Fig. 3 the blocking delay time of transistor 3 is controlled by the voltage at its base, which may be a steady D.C. level or have a modulating signal impressed on it from a microphone 12, the AND gate output pulse width varying accordingly. The feedback circuit of resistor 13 and capacitor 14 makes the circuit essentially temperature independant.
