ABSTRACT:
A battery saver type paging receiver includes an improved peak and valley amplitude detection type data limiter section with mode control operation thereof, digital word storage of acquired peak and valley amplitude values, and self tuning capabilities. More specifically, the data limiter section includes a controller for controlling the peak and valley detection circuits to acquire respective peak and valley amplitude values in digital word form in a first operational mode and to hold the peak and valley amplitude digital words in corresponding storage registers in a second operational mode. The controller may transfer the data limiter section into a third operational mode during which the peak and valley digital words may be altered a predetermined count to effect a self-tuning thereof. In one embodiment, the third mode of operation is effected during the transfer between the second and first modes of operation.
