摘要
提出用下列四种算法对由软件产生的DTMF信号进行解码:FFT算法,DFT算法,卷积法,迭代法。对上述解码算法的实验结果进行了分析和比较,并揭示了它们之间的内在联系。
Four algorithms are proposed to decode the DTMF signal generated by software in this paper： Algorithm, DFT algorithm, Convolution algorithm and iterative algorithm. The results are analyzed and compared with each other, and the internal relations among them are revealed.
