Filed: 1985-06-20
Abstract: PURPOSE:To prevent the frequent change over of a monoral and a stereo or a main signal output and a subordinate signal output by the malfunction of a sound multiplex discriminating circuit by discriminating the degree of the deterioration of a receiving condition by a sound multiplex demodulating circuit, and changing over a receving mode to the monoral or a main signal output condition when the receiving condition is worse than a prescribed condition. CONSTITUTION:The output of a receiving condition discriminating circuit 10 discriminating the receiving condition by an input electric field intensity signal is inputted to a logic circuit 2. The logic circuit 2 takes a receiving condition discriminating signal as well as a mode setting signal and stereo/multi discriminating signal into account to control a matrix circuit. When the average level of the input electric field intensity is lower than the level in which the sound multiplex discriminating circuit begins the malfunction or when the frequency in which the input electric field intensity is deteriorated below the prescribed level is increased, the receiving condition discriminating circuit 10 discriminates the degree of the deterioration of the receiving condition and in accordance with the discrimination, the logic circuit 2 is forcibly changed over to the main signal or the monoral. Thereby, even when the input electric field is changed thereafter, the main and the subordinate are not frequently replaced with each other.

Title: Detecting system for called party unreply
Inventor: NAGATA TAKASHI
IPC: H04M1/27
Filed: 1987-05-30
Abstract: PURPOSE:To attain shorter time detection in comparison with the detection with a prescribed elapsed time by using a measuring time as a new reference time so as to update a storage section when the measured time is over a reference time in detecting a called party unreply. CONSTITUTION:A measuring section 3 starts counting in the case of sending a dial number from a dial sending section 1 and stops the counting when a response detection section 2 detects the reply of the called party. The measured time and the reference time in the storage section 4 are compared by a comparison detection section 5 and when the measured time exceeds the reference time, it is judged that the called party does not reply. Thus, the unreplied called party is detected by the elapsed time corresponding to the deference time. Moreover, in detecting the reply of called party by a detection section 2, the measured time of the measuring section 3 is compared with a reference time stored in the storage section 4 and when the measured time is over the reference time, the measured time is used as a new reference time to update the storage section 4, the reference time is set automatically at the system rising. Moreover, the optimum reference time is updated even during the operation.
