Question

Write the Condition for oscillations.

Answer 1

To start the oscillation with the constant amplitude, positive feedback is not the only sufficient condition.Oscillator circuit must satisfy the following two conditions known as Barkhausen conditions:
1. The firstcondition is that the magnitude of the loop gain (Aβ) must be unity.

Answer 2

To start the oscillation with theconstant amplitude, positive feedback is not the only sufficient condition. Oscillator circuit must satisfy the following two conditions known as Barkhausen conditions: 1. The first condition is that the magnitude of theloop gain (Aβ) must be unity.
