In Astable operation, we have no stable states. Hence we say that timer doesn’t stay in any of the two states indefinitely i.e. vibrates between the two states. Hence we don’t need trigger in this case. This is also called Astable Multi-vibrator. This is also called free-running multi-vibrator. When-ever we give power to the timer, we get the […]

Timing Circuits: Introduction
The timing circuits are the special purpose circuits which are generally used in digital circuits. We have the following important types of timing circuits: 1. 555 Timers are used in timing circuits very often as they are more reliable and lost cost. We have the two modes of operation of 555 Timer: Monostable operation Astable […]
