Oscillator: Introduction and Types

Oscillator image

Oscillator is an electronic device provides a source of the repetitive alternating current signal across its output terminal without needing any input because signal generated is usually of constant amplitude. Common signals generated by the oscillators includes clock signals, sound signals produced by video games, electronic beepers and broadcast signals by television and radio transmitters. In our previous article, we explain about oscillator circuit in brief. Have a look at¬†it. Generally, oscillators are characterised according to the frequency generated at their output signal because for stabilisation different frequencies are required in different areas. For example: For producing signals in the Read More …

It basically converts direct current from a power supply to an alternating current signal. In our previous articles, we explain how we can use a¬†transistor as an amplifier and its configurations. Here we are going to put some shadow on how we use a transistor as an oscillator, its mechanisms and types. Transistor as Oscillator When we use a transistor Read More …
