摘要

对于移动性设备的信号调控问题，传统的 PWM 信号发生器存在精准度低、便携性差等问题。针对相关现状，特基于 FPGA，设计出一款便携式 PWM 信号发生器，可实现占空比以 1％步长可调、频率通过四个按键分别控制实现 100 Ｈｚ、1ｋＨｚ、10 μｓ的最小分辨率在数码管上进行显示。实验结果表明，该系统电路产生的信号稳定可靠，还具有精度高、便携性好等优点。

Abstract:

Traditional PWM signal generators have problems with low accuracy and poor portability in signaregulation for mobile devices. In response to the current situation, a portable PWM signal generator has beerdesigned based on FPGA, which can achieve a duty cycle adjustable in 1% 6 step size and four frequeney pulswidth adjustable square wave signal generators of 100 Hz, 1 kHz,10 kHz, 100 kHz and can be controlled by foubuttons , and finally displayed on a digital tube with the minimum resolution. The experimental results show thathe signal generated by the system circuit is stable and reliable, and it also has advantages such as higlaccuracy and good portability.
