摘要： A signal level detector including a diode envelope detector has a characteristic having both square-law and linear-law ranges separated by an intermediate transition range of variable-law operation. The detector is provided with circuits (38, 47, 48) to extend the linear-law range of the characteristic to overlap at least a part of the variable-law transition range. A circuit (66) is provided to detect operation through an input signal level transition point between said square-law range and the extended linear-law range for automatically modifying (39) the level detector circuit so that the voltage output thereof is continuously indicative of input power level through all of said ranges.

摘要： To stabilize the phase of bit rate clock signals recovered from a self-clocking data signal, e.g., a Manchester coded signal, extra signal level transition pulses (58) occurring during intervals of successive bits of the same info bit type are inverted (59) to reinforce the desired phase of the bit-rate frequency component.
