Title: Abnormality detection system for radio transmission and reception equipment
Inventor: AKUTSU SHIYOUJI
IPC: H04B17/29
Filed: 1989-06-21
Abstract: PURPOSE:To accurately detect non-modulation and line disconnection by comparing the level of the output detection signal of a level detector and that of a preliminarily set reference voltage with each other and outputting an abnormality detection signal having a prescribed level at the time of the occurrence of abnormality. CONSTITUTION:When a modulated wave is inputted in an input level lower than a designated value, the level of the clock component taken out from a filter circuit 42 is lower than the reference voltage. Consequently, the output signal of a comparator 44 is the abnormality detection signal having a prescribed level. If a reception signal is a non-modulated wave which is not modulated by a digital signal to cause abnormal reception, the clock component is not taken out from the filter circuit 42 even if the reception input level of the non-modulated wave is the prescribed abnormality value or lower than the prescribed value. Consequently, the output signal of the comparator 44 is the abnormality detection signal having the prescribed level because the output detection signal level of a level detector 43 is lower than the reference voltage. Thus, the non-modulated wave input is accurately detected.
