Generators and pulse shapers for logic elements

If the input trigger pulse duration less than the period of oscillation is generated at the outputs of a single pulse. When more layers control the duration of the output signal will pack shown in the diagram. Fig. 21 is a diagram of relatively long pulse shaper (monostable) and its timing diagram. One-shot is made on two elements - NOT. The structure of many amateur radio devices include pulse generators, which are now often build on elements of transistor-transistor logic [I]. At high values ​​of the frequency of such generators usually work well.
