Description: 以SPCE061A单片机（ Single Chip Micyoco）为核心，通过DDS合成技术设计制作了一个步进值能任意调节的多功能信号源。该信号源在1KHz～10MHz范围能输出稳定可调的正弦波，并具有AM、FM、ASK和PSK等调制功能。信号输出部分采用低损耗电流反馈型宽带运放作电压放大，很好地解决了带宽和带负载能力的要求。系统带中文显示和键盘控制功能，操作简便，实现效果良好。
内含 原程序，正弦信号发生器的pCB原理图，以及一些相关论文。-to SPCE061A (Single Chip Micyoco) at the core, DDS technology through the design of an arbitrary value of Step-conditioned multi-purpose signal source. The signal source in a KHz - 10MHz range stability can be adjustable output sine wave, with AM, FM, ASK and other PSK modulation functions. Part of the output signals using low loss current-feedback operational amplifier for wideband voltage amplification and very good solution with the bandwidth and load capacity requirements. Chinese system with display and keyboard control functions, simple operation, achieving good results. Intron original program, sinusoidal signal generator pCB diagram, and a number of related papers.

Description: Proteus软件是Labcenter Electronics公司的一款电路设计与仿真软件，它包括ISIS、ARES等软件模块，ARES模块主要用来完成PCB的设计，而ISIS模块用来完成电路原理图的布图与仿真。Proteus的软件仿真基于VSM技术，它与其他软件最大的不同也是最大的优势就在于它能仿真大量的单片机芯片，比如MCS-51系列、PIC系列等等，以及单片机外围电路，比如键盘、LED、LCD等等。通过Proteus软件的使用我们能够轻易地获得一个功能齐全、实用方便的单片机实验室。-Proteus Software is a company Labcenter Electronics circuit design and simulation software, which includes the ISIS, ARES, such as software modules, ARES module is mainly used to complete the design of PCB, and ISIS modules to complete the circuit schematic diagram of the layout and simulation. Proteus software simulation technology based on the VSM, which is the biggest difference between other software' s greatest strength is that it is a large number of single-chip-chip simulation, such as the MCS-51 series, PIC series, etc., as well as single-chip peripheral circuits, such as keyboard, LED, LCD and so on. Through the use of Proteus software we can easily obtain a fully functional, practical and convenient single-chip microcomputer laboratory.
