Abstract

1373784 Pulse regenerators SIEMENS AG 8 Oct 1971 [30 Oct 1970] 46860/71 Heading H3P Pulses occurring in periodic time slots are regenerated by integrating the pulse during each slot, monitoring the output of the integrator to determine the identity of the pulse and using the output of the monitor to set a bistable circuit upon the occurrence of a timing pulse. In Fig. 1 the incoming pulses are integrated by circuit RC during each time slot and the integrator is reset by contact K at the end of the slot. The monitoring circuit W detects whether the output of the integrator has risen above a given value and sets correspondingly a bi-stable circuit F in response to a timing pulse occurring at the end of the slot. As described, the incoming pulses are bipolar and the circuit detects whether the pulse is positive or negative of zero. Fig. 7 receives signals in which successive "1" signals are represented by pulses of opposite polarity and a "0" is represented by a zero signal (Fig. 8g). These signals are continuously integrated by a circuit R-C to provide waveform 8h. Monitor W_ detects whether this waveform is above or below a threshold value, providing waveform 8i and this sets a bi-stable circuit in response to clock pulses k to produce an output waveform 81. The original data can be recovered from this by a pulseshaper P.
