Abstract
The invention comprises a digital detector used in a paging system. This detector has reference levels, against which the received signal is compared with a digital comparator (11). The reference levels can be changed with an updating logic (12), if changes are observed in the levels of the received signals. The detector may also compensate for differences between individual FM detectors.
