ABSTRACT
Practice in the production and extensive use of various types of signal generating circuit, on the waveform, it may be sinusoidal and non-sine wave. Can produce stable, periodic changes over time, the output waveform of the device into the signal generator, also known as the oscillation circuit. They do not need to be able to produce different kinds of periodic input signal waveform, the measurement, communications, radio technology, automatic control and heat processing has been widely applied in many fields. Add in the function signal generator waveform converter can achieve a square wave, triangle wave, sine wave of one another, and to include amplitude and frequency adjustment device to achieve the goal of the experiment. The following is the subject of experimental programs. Altium Designer , based on a software integration platform, provide a complete electronic product development environment all the tools needed to integrate in an application. Altium Designer contains all the tools needed to design task: principle diagram and HDL design input, circuit simulation, signal integrity analysis, PCB design, embedded system based on FPGA design and development. In addition to Altium Designer customization work environment, to meet various needs of users. 【 Key words 】 ： AD DXP ， PCB design tools ， schematic design ， automatic routing ， principle of mixed-signal simulation
