Abstract :
Depending on the characteristics of frequency shift track signal, this paper presents a method of concerning band-pass sampling and processing the Frequency-shift signal with ZFFT, which can satisfy the demand of precision. According to the characteristics of frequency spectrum of Frequency-shift signal, this paper suggests to make use of OMAP L1x to realize a high resolution detection of Frequency-shift signal. At the same time it also gives a hardware block of the system and at last it analyzes real-time of the system. This system has such advantages of easy extensibility, fast processing speed, high precision. These advantages offer foundation to design perfect performance and multifunction Frequency-Shift detection device.
