ABSTRACT:
An analog "blue" signal detector detects when the amplitude of a spectral component of an input signal associated with a blue signal exceeds a given level for a predetermined period of time to provide an indication that the blue signal is present. When the blue signal is removed, the indication is rapidly removed also.
