explain the principle of working of transister as a oscillaters
Answers
Answer:
Transistor amplifier as an oscillator: In an oscillator, the output at a desired frequency is obtained without applying any external input voltage. ... The inductive coupling between coil T2 and T1 cause a current to flow in the emitter circuit i.e., feedback from input to output.

Explanation:
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.
Oscillators convert a DC input (the supply voltage) into an AC output (the waveform), which can have a wide range of different wave shapes and frequencies that can be either complicated in nature or simple sine waves depending upon the application.
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.
