出判定回路。 The transmission/reception code of the paging system is composed of a periodic code, a frame code, a group code, an address code, a data code, and a checksum, and the group code is a group of bits indicating how many bits of the upper bits of the address code should be checked. The address code is a group of bits indicating the slave station to be called, and includes a counter section that sets the number of bits to be verified indicated by the group code, and a counter section that reads an address from the address code and stores the read address bits. and a processing section that sequentially collates the address bits of the slave stations bit by bit, increments the counter value if they match, and determines that a group call is being made when the counter value reaches 0. Group call determination circuit of paging device.
