Abstract
714,442. Pulse generating circuits. PYE, Ltd. Dec. 24, 1952 [Dec. 24, 1951], No. 30165/51. Class 40 (6). [Also in Group XXXV] A circuit for producing the waveform shown in Fig. 3 comprises a triode valve V, Fig. 4, fed on its grid with a sine-wave voltage and with a condenser C2 connected across anode and cathode. The saw-tooth voltage normally produced on this condenser is combined with a sinewave voltage fed from the grid input via a condenser C1 and resistor R3 to a tapping on the anode resistor R1.
