Abstract
Depending on the characteristics of Frequency-shift track signal,this paper presents a method concerning band-pass sampling and ZFFT to process the Frequency-shift signal, which can satisfy the demand of precision. According to frequency spectrum characteristics of Frequency-shift signal, this paper suggests to make use of OMAP Llx for realizing a high resolution detection of Frequency-shift signal. It also gives a hardware block of the system and analyses real-time of the system. This system has such advantages as easy extensibility, fast processing speed, high precision. These advantages offer foundation to design perfect performance and multifunction Frequency-Shift detection device.关键词
