Signal level control for an amplifier or the like is provided by a binary counter which counts upward when first operated, and which thereafter counts up and down if continually operated. If the operated counter is stopped after counting up, it counts up when operated again. If the operated counter is stopped after counting down, it counts up when operated again. A digital to analog converter can provide a single control signal from the counter. The user is always assured that the single control signal will increase when the counter is operated again following a prior operation in either direction.

Circuit for controlling the output level of an electronic device

A paging receiver selectively operable in either a six tone battery saving mode or in a five tone non-battery saving mode. The receiver features a serial code plug for programming a programmable tone detector to be responsive to a specific paging receiver address comprising a predetermined combination of preamble and paging signals. The use of a serial code plug in place of the parallel code plug previously known and utilized in the industry allows a reduced complexity of the paging receiver and a corresponding size, weight and cost savings.
