The Study on the Test Model about the Electromagnetic Inductive Communicating Signal Quality

The article analyzes the quality checkout methods of different signals, carrying on the concrete analysis at the concrete characteristic about the signal of electromagnetic inductive communicating. Analyze the quality circumstances of waveform with the input / export signal contrast, and environmental influencing factors like power supply voltage and metal environment, transmission distance and electromagnetic environment could lead to transmit without thread fail, Get a mathematical model which can directly perceived the signal quality state with the threshold value law establishment.
