The circuit of a fixed bias bistable multivibrator is shown in Fig. 31.30 (a). It consists of two identical transistors Q 1 and Q 2 with equal collector resistors R C1 and R C2 and with output of one supplied to the other. The feedback is coupled through resistors R 1 and R 2. The output may be taken from either of the two transistors Q 1 and Q 2.

Circuit Explanation. The Astable multivibrator consists of two cross-coupled RC amplifiers. The circuit has two unstable states. o When V1 = LOW and V2 = HIGH then Q1 ON and Q2 OFF. o When V1= HIGH and V2 = LOW then Q1 OFF and Q2 ON. In this R1 = R4, R2 = R3, R1 should be greater than R2. C1=C2.

A multivibrator circuit oscillates between a "HIGH" state and a "LOW" state producing a continuous output. Astable multivibrators generally have an even 50% duty cycle, that is that 50% of the cycle time the output is "HIGH" and the remaining 50% of the cycle time the output is "OFF". In other words, the duty cycle for an ...

The vibration of an electromagnetic feeder is generated as the alternating electrical current moves back and forward through the wires of the coil. As the current moves in one direction, the coil attracts the magnet and adds tension to the springs. When the current switches direction the magnet is released, and the potential energy stored as ...

Let us now move further and understand the working of a bistable multivibrator. As the power supply is provided both the transistors come into conducting state. As we know that no two transistors are exactly equivalent and show some variation in their operating principle. Thus, one of the transistors conducts more than the other.

In monostable multivibrator there is one stable state and one astable state. This multivibrator need a trigger (external signal) to enter into the astable state and get back to the stable state after some time period. The time period will be set by the user, the monostable multivibrator is mainly used as timer.

SW-420 Working Principle. The SW-420 is a switch that operates by the opening and closing of the electrical contact. By default, the vibration sensor is in a closed state. When no vibrations are sensed, it remains closed or in a conduction state. As soon as vibration is detected by the sensor, the contacts open and the resistance rises.
