This paper aiming at the characteristic of the ASK signal in audio frequency track circuit without insulation presents a new algorithm to demodulate the ASK signal-the demodulation algorithm of ZFFT, designs a demodulation system on the basis of TMS320C32. The result of experimentation shows that the system can demodulate the ASK signal reliably. It accords with the requirement in locale.
