摘要:
在研究微硬盘读写通道时,模拟伺服信号的信号发生器必不可少。本文研究了一种基于DSP和FPGA直接数字频率合成技术组成的程控信号发生器,其频率分辨率可达0.001H z,波形输出的频率、幅值和相位精度高,稳定性好,且失真度低。该方法与传统实现方式相比,电路实现简单、易修改,便于程控并可模拟各种伺服信号。

Abstract:
The device for servo signal generation is necessary for reading and writing the channel of micro hard disks. This paper studies a programmable signal device by the direct digital frequency synthesis technology based on DSP and FPGA. This device has a high frequency resolution of 0. 001Hz, a high precision of frequency, phase and amplitude of output wave, good reliability,and little distortion. Compared with general devices, this device can generate a ll kinds of servo signals, and the circuitry is simple, reliable and programmable.
Key words: (servo signal, DSP, FPGA, digital synthesis)
