摘　　要：本文提供一种气象传真信号数字化分析的有效方法.利用气象传真机(或单边带短波收音机)接收气象信息,它以音频的格式输出,但气象传真信号已被接收并加载在此音频信号上.现具体分析包括采样、量化、编码和数字处理等过程,并完成在MATLAB仿真与实验.The subject tissue an effective methods that analysis a meteorological fax signal in digital manner. We can use weather fax （or single sideband shortwave radios） to receive weather information, which is output in audio format. But weather fax signal has been received and loaded on the audio signal. A specific analysis is used to handle process including sampling, quantization,coding and digital processing, and accomplish the MATLAB simulations and experiments.
