Abstract
In a selected paging signal type receiving apparatus, a transmission code is received which is arranged by coupling a series of signal codes including a preamble, a sync code, and a message code. Even when signal reception is interrupted, this receiving apparatus can immediately respond to an interference condition and a completion of a signal transmission. In the case of the interference condition, the receiving apparatus can be immediately recovered to the signal reception operation after the interference condition disappears. This selected paging signal type receiving apparatus with a simple arrangement is arranged by a sync signal generator for generating a signal having the same time period as that of the sync code, and reset when the preamble is detected; a receiving circuit intermittently operated in response to the sync signal from a sync signal generator; a sync code detecting circuit and a preamble detecting circuit intermittently operated in response to this sync code; and also a paging code detecting circuit operated only when the sync code is detected.
