In this video, the design of the Monostable Multivibrator using the transistor (BJT) is explained. In this video, the operation (working) of the Monostable multivibrator circuit is explained in detail and in the end, the equation of the time duration for which the circuit goes into the unstable state is derived. By watching this video, you will learn the following topics: 0:00 Introduction 0:23 What is Monostable Multivibrator? (A brief introduction) 0:53 Description of the Monostable Multivibrator Circuit 2:28 The operation (working) of the Monostable Multivibrator 7:33 The derivation of the time duration expression of Monostable Multivibrator What is Monostable Multivibrator? The monostable Multivibrator has one stable state. But whenever the trigger signal is applied then momentarily the output goes into the unstable state. The time duration for which the output goes into the unstable state can be controlled by the external resistor and capacitor. The monostable multivibrator can be used in the following applications: 1) Generating Time Delays 2) Switching the Relays 3) To generate Pulse Width Modulated (PWM) Output 4) Frequency Division In this video, the Monostable Multivibrator is designed using the BJT and its working is explained in detail. And in the end, the expression of the time duration is derived. The time duration for which the Monostable Multivibrator goes into the unstable state can be given as T = 0.693 R2*C (Here the nomenclatures are used as per the video.)
