The pulse detector is classified as a monostable multivibrator because it has only one stable state. |
This circuit does not have the monostable multivibrator macro between the switch bounce waveform and the counter. |
There is no stable state where the circuit can come to rest, so this circuit is known as an astable multivibrator. |
The monostable multivibrator, or one-shot, is designed to generate controllable-duration pulses when triggered by the rising or falling edge of a trigger clock. |
Like the astable multivibrator, one transistor conducts and the other cuts off when the circuit is energized. |
