Title: Reception signal cutoff detecting system
Inventor: TANABE NAOTO
IPC: H04J3/14
Filed: 1989-03-16
Abstract: PURPOSE:To accurately detect the cutoff of a reception signal even in the neighborhood of OdB of the C/N of the reception signal and to detect hit by monitoring not only the envelope of the reception signal but the state of a reception frame, and generating an alarm for the cutoff of input when both former and the latter are not set at synchronous states simultaneously. CONSTITUTION:A signal taken out from a frequency converter 11 is converted into original information data via a demodulator 12 and a decoder 13, while, it is envelope- detected at an envelope detector 14. A frame synchronizing signal is detected at a frame synchronizing part 15, and a frame synchronous state is stored in a synchronous state storage part 16. And at an alarm generating part 17, the alarm for the cutoff of the reception signal is generated based on the output signals of the envelope detector 14, the frame synchronizing part 15, and the synchronous state storage part 16 when a prescribed condition is satisfied. Thereby, it is possible to prevent the fact that the C/N of the reception signal goes in the neighborhood of OdB due to the quantity of rain fall from being erroneously detected as the cutoff of the input when demodulation data can be obtained normally, and to accurately detect the cutoff of the input after the step out of frame synchronization occurs, and also, since a response time can be shortened, and the hit of the reception signal can be detected.

Abstract: PURPOSE:To enable removal of a harmonic content of the frequency of an alternating- current signal at all times even when the frequency fluctuates, by detecting the frequency of the alternating-current signal from an output signal of a digital filter and by adjusting the gain characteristic of the digital filter so that it is matched with the detected frequency. CONSTITUTION:A signal obtained by sampling an alternating-current signal and subjecting the sampled signal to A/D conversion is inputted to an adaptive digital filter 1a, and a signal of a specified frequency component is extracted therefrom and outputted to a peak value detecting processing element 1b and a frequency detecting processing element 1d. A peak value of the signal is calculated by a prescribed formula in the processing element 1b, and based on the peak value, an effective value is calculated by a prescribed formula in an effective value calculating arithmetic element 1c. Based on the frequency of the alternating-current signal detected in the processing element 1d, such a filter coefficient as to make the detected frequency by the central frequency of the filter 1a is calculated in a filter coefficient calculating processing element 1e. According to this coefficient, the gain characteristic of the filter 1a is adjusted. Thereby the gain of the alternating-current signal inputted to the filter 1a can be made invariable at all times even when the frequency of the alternating-current signal fluctuates.
