How can a transistor be used as an oscillator?

A transistor can be operated as an oscillator for producing continuous undamped oscillations of any desired frequency if tank (or oscillatory) and feedback circuits are property connected to it. All oscillators under different names have similar function i.e. they generate continuous undamped output.

What is oscillator explain transistor as an oscillator?

Oscillator is an electronic circuit that produces a periodic, oscillating signal often a square wave and a sine wave. 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.

Which principle is used for oscillator?

There are many types of electronic oscillators, but they all operate according to the same basic principle: an oscillator always employs a sensitive amplifier whose output is fed back to the input in phase. Thus, the signal regenerates and sustains itself. This is known as positive feedback.

What is an oscillator explain use of transistor as oscillator under following points a Labelled Diagram B working?

The energy is taken from the collector circuit and is fed to the base circuit. This is how a transistor works as an oscillator. Explanation: When the transistor is used in a circuit of an oscillator it starts working as an amplifier.

How is transistor used as an amplifier?

A transistor acts as an amplifier by raising the strength of a weak signal. The DC bias voltage applied to the emitter base junction, makes it remain in forward biased condition. Thus a small input voltage results in a large output voltage, which shows that the transistor works as an amplifier.

How is transistor used as a switch?

One of the most common uses for transistors in an electronic circuit is as simple switches. In short, a transistor conducts current across the collector-emitter path only when a voltage is applied to the base. When no base voltage is present, the switch is off. When base voltage is present, the switch is on.

What is transistor example?

The definition of a transistor is an electronic device that works by controlling the flow of the electrical current. An example of a transistor is something combined in large numbers with microcircuits into a single circuit board and used in a computer. An optical transistor.
