Abstract
Radio frequency energy detection circuitry for changing the logic state of an output signal from an initial state to a second state in response to received radio frequency energy exceeding a first predetermined power level, such circuitry being non-responsive to fades in such received radio frequency signal by preventing the second state of the output signal from reverting to the initial state until the power level of the received radio frequency energy falls below a second, lower predetermined power level.
