On further discussion of Barkhausen criterion

It has been pointed out that Barkhausen criterion cannot be used as a general oscillation condition, to evaluate (1) growth of oscillation, (2) steady state amplitude of oscillation in terms of circuit and active device parameters and (3) to as certain amplitude and frequency stability of oscillation, (4) to audit the nature of oscillation whether it is soft-self or hard-self excited. Here it has been shown that all these limitations can be over come through clubbing of quasi-state and quasi-linearization techniques and modified Barkhausen criterion can also be applied to four terminal as well as two terminal oscillators.
