Pulse shaper

On the basis of the logical components of digital devices can be designed a variety of pulse generators. Here are a few specific examples. The on-chip digital devices play an important role different pulse shapers - from buttons and switches of the signals with flat fronts, differentiating circuit, and multivibrators. This section of the book discusses some questions of constructing such generators and generators series of CMOS chips. For the formation of short pulses in games there are two methods: a derivation of the input pulses and pulse shaping using logs­cal circuits. Fig. Generator of short pulses with a delay line. Short pulse generates pulses whose duration is considerably shorter than the initial pulses. Pulse generators are used in many electronic devices (electronic counters, time relay) is used for configuring the digital technology. The frequency range of such generators may be from a few hertz to many megahertz.

3 are considered circuit generates output pulses of predetermined duration for input control signala.Dve of these short pulses are formed at the front of the signal, and the third (one-shot) forms a long pulse of short input. Known pulse shapers, pre- designated 5 for temporarily matching the input signal with the clock pulses computer containing triggers conditioners, AND-NO elements, inverters (1). However, these schemes are complex formers l0, also known pulse shaper comprising three flip-flop, two AND element HE (21. However, this driver does not allow 15 is derived from the sequence of non-synchronized signals synchronized sequence of pulses whose duration is equal to the period of operation clock. The generator can be constructed at the NOR gate, NAND or NOR. Consider a simple oscillator circuit at two logical NAND.

It simply refers forming linear chains, such as distributed or lumped parameters, and nonlinear shaping circuit, for example. Pulse shaper FIs can work on the principle of converting the light flux from the source LN (LED, incandescent and so on. N.) Special photodetector (photoelectric cell, photodiode), closed the narrow aperture in the current or voltage pulses that occur at the time of the passage of slots (short pulses Mu in Fig.

Of great importance in practice have the short-pulse, also called "assignment scheme fpontov" ^ Fig. 16.6, and a diagram which makes it, as expected from the effect of signal delay in the logic element.
