SVPWM
- 变频驱动主要使用的驱动波形主要有SPWM和SVPWM两种。SPWM原理简单、实现容易,是现在使用最广的一种变频驱动波形。但其有一个致命的弱点是其电源利用率不高（只有86％）、谐波成分大。因此,在新近开发的产品中其应用逐渐被性能优异的SVPWM所取代。SVPWM是一种电压利用率、低谐波成分的变频驱动波形,还有开关次数少、功率管功耗小等特点。同时,SVPWM还能很好的结合矢量控制算法、以最大限度的发挥设备的性能。因此被越来越多的变频设备所采用。-The main use of variable f

GMSK
- GMSK是高斯滤波的最小频移键控的简称，基本的工作原理是将基带信号先经过高斯滤波器成形，再进行最小频移键控(MSK)调制。由于成形后的高斯脉冲包络无陡峭边沿，亦无拐点，因此频谱特性优于MSK信号的频谱特性。-GMSK Gaussian filter is the smallest FSK abbreviation, the basic working principle is to base-band signal to pass Gaussian filter shape, and then

VHDL
- 在电子技术中，频率是最基本的参数之一，又与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速，以及便于实现测量过程自动化等优点，是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计，并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门，通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率，最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题
