WebMar 4, 2011 · These two conditions for sustained oscillations are called Barkhausen criteria. There is no need of an input signal for the initiation of oscillations. In order to obtain a self-sustained oscillation, the condition β A = 1 must be satisfied. The value of β A is made greater than unity. As a result the system starts oscillating by amplifying ... WebIn an oscillator, Barkhausen criterion Aβ is equals to 1, because for this condition only the output voltage is sine wave under steady state condition. Hence, option C is correct. If Aβ is zero, then the product of Aβ and input voltage ( v in) will also be zero.

The Barkhausen effect is a name given to the noise in the magnetic output of a ferromagnet when the magnetizing force applied to it is changed. Discovered by German physicist Heinrich Barkhausen in 1919, it is caused by rapid changes of size of magnetic domains (similarly magnetically oriented atoms in ferromagnetic materials).
