1,064,620. Transistor pulse circuits. XEROX CORPORATION. Dec. 9, 1965 [Dec. 17, 1964], No. 52189/65. Heading H3T. The subject matter of the present Specification is mostly contained in Application No. 52190/65 but the claims relate to the switching of the output level between its two values in dependence upon the input pulses reaching a given energy level. The circuit described omits the signal amplitude control circuit, and the feedback to the integrator is accordingly effected by a transistor (Q6) having emitter and collector series diodes (SR1), (SR2) to limit the voltage swing. In addition the circuit is preceded by an amplifier (10) having automatic gain control. |
