PURPOSE:To enable an operator on the data reception side to easily detect the reception state by providing a reception state discriminating device and automatically discriminating whether the reception state is good or not by this device and displaying the discrimination result on a display device. CONSTITUTION:Data transmitted by a radio line passes an antenna and a receiver is demodulated to digital data and is inputted to an error correcting device 2 and has error corrected, and correct reception data is inputted to a data processor 3. Meanwhile, a reception state discriminating device 4 detects the number of error correction bits based on the correction result of the error correcting device 2 and discriminates whether the number of error correction bits exceeds a set value or not and discriminates whether the reception state is good or not in accordance with this discrimination result. The discrimination result is inputted to a display device 5 and is displayed with characters or a picture to inform the operator or the like whether the reception state is good or not. |
