16BITE_PWM

这个事利用超声波模块测距然后通过串口发送到电脑的一个程序，适合上手学习超生波的同学(This use of ultrasonic module ranging through a serial port and then sent to a computer program, suit to students learning super living wave)

高效DPD算法在无线基站设备中，末级功率放大器的失真是影响无线带宽的主要因素之一。当前业界的主流解决方案是采用数字预失真技术，在下行信号中加入失真补偿分量以对消PA输出的失真成分，达到提升带宽的目的。(The distortion of the amplifier is one of the main factors that affect the wireless bandwidth. The mainstream solution of the industry is to use digital pre distortion technology, in the downlink signal to join the distortion compensation component to eliminate the distortion of the PA output components, to achieve the purpose of improving the bandwidth.)

数字电子时钟是一种使用数字电路技术实现时钟、分钟和秒钟定时的设备。 它在其他电子时钟中具有更高的准确性和主观性。数字钟包含扩展功能和基本功能。其中，基本功能部分：以数字形式准确定时，显示时、分、秒的功能; 扩展功能部分： 日期显示、闹钟、温度显示。(A digital electronic clock is a device that uses digital circuit technology to achieve clock, minute, and second timing. It has higher accuracy and subjectivity in other electronic clocks. The digital clock has two parts, basic functions and extended functions. Among them, the basic function part: accurate timing in digital form, display hours, minutes, seconds function; extended function part: date display, alarm clock, temperature display.)
