Abstract
A new sufficiency proof for the Nyquist criterion is obtained via the analyticity properties of the log function. The intuition derived therefrom is then used to formulate a generalized stability criterion applicable to feedback systems whose open loop gains are characterized by arbitrary Lipschitz continuous unbiased operators.
