PROBLEM TO BE SOLVED: To individually detects ATC receiver abnormalities generated in the ATC receiver which processes an analog ATC signal in an analog signal processor composed of an A-D converter and a low-pass filter, and also processes the digital-processed ATC signal in a deplex digital signal processor composed of a CPU and a digital signal processor.SOLUTION: The ATC signal being an analog signal is simultaneously digital-converted in parallel by the dublex LPF and the ADC, each ADC output is processed by the duplex DSP and the CPU, and failures in the ATC receiver including the CPU are individually detected with bus reference to data received during processing and CPU input/output data. |
