Pulse signal control circuits

摘要

A first diode having a polarity opposite to the diode characteristic between the emitter and base electrodes is connected across these electrodes of a first transistor, a resistor having a high resistance is connected between the collector and the base electrodes of the first transistor and a first source of high reference potential is connected to the collector electrode. The collector electrode of a second transistor is connected to the base electrode of the first transistor and to a second diode and the emitter electrode of the second transistor is connected to a second source of low reference potential. A high frequency pulse signal is applied to the collector electrode of the second transistor through the second diode, and a pulse data signal containing a high frequency pulse signal synchronous with the first mentioned high frequency pulse is applied to the base electrode of the second transistor thereby producing an amplified pulse data signal containing a high frequency pulse signal corresponding to a data input signal on the emitter electrode of the first transistor.
