1. pulse forming
The monostable trigger can generate a pulse with a certain width, and an input pulse that is too narrow or too wide can be integrated into a pulse with a fixed width for output.
The irregular input waveform shown in Figure 6-9, after being processed by monostable trigger, can obtain regular rectangular wave output with fixed width, fixed amplitude and steep rising and falling edges.
2. Pulse sequence:
If the output Vo of the monostable trigger is connected to one input pin of the AND gate, the other input pin of the AND gate inputs the high-frequency pulse sequence Vf. When the input negative narrow pulse arrives, the monostable trigger starts to flip and the AND gate opens, allowing the high-frequency pulse sequence to be output from its output terminal VAND through the AND gate. After the tpo timing time, the monostable trigger returns to the steady state, and the AND gate is closed to prohibit the output of high-frequency pulse sequence. So as to realize the timing gating function of the high-frequency pulse sequence.
