1.	In an oscillator, for sustained oscillations, Barkhausen criterion is `Abeta` equal to (A = voltage gain without feedback and `beta` = feedback factor)A. zeroB. `(1)/(2)`C. 1D. 2
Answer» Correct Answer - C According to question, Barklhausen criterion states that if A is the gain of the amplifying element in the circuit and B is the gain of the amplifying element in the circuit and B is the transfer function of the feedback path, then condition of sostained oscillation is given by `\|betaA\|=1` So, option (c) is correct.
