Title: Receiver
Inventor: MURAHATA KATSUYUKI
IPC: H03J7/18
Filed: 2004-01-08
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a mute time for checking the receiving state of a radio receiver for an alternate frequency (AF) station, thereby eliminating an uncomfortable feeling due to sound break.  <P>SOLUTION: A latch circuit 26 is provided for holding N-value (the frequency division ratio of a frequency divider circuit 21) data transmitted from a microcomputer 30 for receiving an AF station. After sending the N-value data of the AF station to the latch circuit, it transmits a mute signal to a muting circuit 18. After the muting circuit detects a zero cross of audio signals, it sets mute on and changes the N-value for receiving a now listening broadcast station to the N-value of the AF station held in the latch circuit to receive the AF station. After checking an AF station receiving state, the microcomputer returns the N-value to the original one and cancels the mute to receive an original broadcast station if the AF station receiving state is unfavorable, and cancels the mute to receive the AF station if the AF station receiving state is favorable. Compared with a conventional system of transmitting the N-value data of the AF station to a PLL circuit 20 after muting, the mute time is reduced by the N-value transmitting time.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
