Astable Circuit (Oscillator)

An astable circuit (as opposed to a bistable circuit) is not stable in any of its 2 states - continually switching from one state to the other (oscillation).

Electronic oscillators are widely used as clock generators and can be found within flashing light circuits, buzzers, calculators, computers and many other devices.

 

Astable Circuit (Oscillator)

Our interactive classroom version of an astable circuit inlcudes 4 resistors, 2 capacitors and 2 transistors. With power on, the circuit will oscillate between its 2 unstable states, as the charging of each capacitor turns its associated transistor on, and the other transistor off. 

Using the integrated digital multimeter and oscilloscopes on the left of the screen, circuit operation can be demonstrated or observed. The instructor or the student is also provided with the flexibility of running the simulation in various modes, such as Key Event Mode, which automatically pauses the simulation whenever events designated as key events occur.

This item is part of a package of 3 interactive circuits which include:
