说明：  设计一个正弦信号发生器，使用凌阳公司的16位单片机SPCE061A作为中央控制器，结合DDS芯片AD9850，产生0～15MHz频率可调的正弦信号,正弦信号频率设定值可断电保存；使用宽频放大技术，在50Ω负载电阻上使1K～10MHz范围内的正弦信号输出电压幅度VP-P=6V±1V；产生载波频率可设定的FM和AM信号；调制信号为1KHz的正弦波，调制信号的产生采用DDS技术，由CPLD和Flash ROM加上DAC进行直接数字合成；二进制基带序列码由CPLD产生，在100KHz固定载波频率下进行数字键控，产生ASK，PSK信号。(Design of a sinusoidal signal generator, the use of Sunplus 16-bit MCU SPCE061A as the central controller, combined with DDS chip AD9850, have adjustable frequencies 0 ~ 15MHz sinusoidal signal, sinusoidal signal frequency settings can be stored power using broadband amplification, in a 50Ω load resistor to 1K ~ 10MHz sinusoidal signal within the output voltage amplitude VP-P = 6V ± 1V generating the carrier frequency of the FM and AM can be set signal 1KHz sine wave modulation signal, modulated signal generation using DDS technology, coupled by the CPLD and Flash ROM DAC for direct digital synthesis binary baseband sequence code generated by the CPLD in a fixed carrier frequency 100KHz digital keying, resulting in ASK, PSK signals.)

单片机是一种集成电路芯片，是采用超大规模集成电路技术把具有数据处理能力的中央处理器（CPU），随机存储器（ＲＡＭ），只读存储器（ＲＯＭ），多种Ｉ／Ｏ口和中断系统、定时器／计数器等功能（可能还包含显示驱动电路、脉宽调制电路、模拟多路转换器、Ａ／Ｄ转换器等）集成到一块硅片上构成的一个小而完善的微型计算机系统。(Singlechip is an integrated circuit chip. It is a central processor (CPU), random memory (RAM), read-only memory (ROM), a variety of I / O ports and interrupt systems, timer / counter and so on. The circuit, the pulse width modulation circuit, the analog multiplexer, the A / D converter, etc. are integrated into a small and perfect microcomputer system made up of a piece of silicon chip.)
