Design of General Modulated Signal Generator Based on DSP Builder 基于DSPBUILDER的通用调制信号发生器设计
A new scheme is developed in which the phase modulated signal generator is designed for optical fiber sensor, based on the single_chip computer and quasi_DMA technique, to resolve the problems of interference optical fiber sensor with which the signal is difficult to generate and control. 针对干涉型光纤传感信号不易产生,不易定量控制的问题,给出了一种基于单片机技术和类似于DMA技术的低成本相位调制信号发生器实现方案。
A phase modulated signal generator for optical fiber sensor's study 用于光纤传感器研究的相位调制信号发生器
It can be used as the local oscillator in wave/ spectrum analyser. It also can be used as a new digitally modulated FSK/ PSK signal generator. 它可用作为波形、频谱分析仪的本机振荡器,也可用作为数字调制的移频键控(FSK)、移相键控(PSK)信号发生器。
Also, we have described the FPGA design of the whole system including key modules like Modulated Signal Generator and Receiver. 本文还详细介绍了全数字高精度激光测距系统的结构以及调制信号发生器和接收器等关键模块的FPGA实现问题。
