模拟十进制数到二进制数的转换过程，以LED来模拟各个二进制位，并能以动画方式模拟计数的过程。
选择手动方式时，将8个LED变成滑动条中数字的二进制（基数2）表示。例如，如果滑动条设置为数字10（在二进制中表示为00001010=（23）+（21））， LED的1和3点亮，其他LED为熄灭。
选择自动方式时，滑动条自动进行加1操作，实现0到255的循环计数；同时8个LED会实时显示滑动条数值所对应二进制数值。当滑动条大于255时，自动回0并重新由0开始计数。
Simulate the conversion process from decimal number to binary number, simulate each binary bit with LED, and simulate the counting process by animation.
When manual mode is selected, the 8 LEDs are changed into binary (Radix 2) representation of the numbers in the slider. For example, if the slider is set to the number 10 (represented in binary as 00001010 = (23) + (21)), 1 and 3 of the LEDs are on and the other LEDs are off.
When the automatic mode is selected, the slide bar will automatically add 1 to realize the cycle counting from 0 to 255; at the same time, 8 LEDs will display the binary value corresponding to the sliding bar value in real time. When the slider bar is greater than 255, it will automatically return to 0 and start counting from 0 again. (2020-11-28, LabView, 11KB, 下载0次)
功能要求：
用该调幅波解调器可观察调幅波，以及经过巴特沃斯滤波器后的解调信号波形。
调制解调原理：
调制解调器由发送、接收、控制、接口、操纵面板及电源等部分组成。数据终端设备 以二进制串行信号形式提供发送的数据，经接口转换为内部逻辑电平送入发送部分，经调制电路调制成线路要求的信号向线路发送。接收部分接收来自线路的信号，经滤波、反调制、电平转换后还原成数字信号送入数字终端设备。
The AM wave demodulator can be used to observe the AM wave and the demodulated signal waveform after Butterworth filter.
Principle of modulation and demodulation:
Modem consists of sending, receiving, controlling, interface, control panel and power supply. The data sent by the data terminal equipment in the form of binary serial signal is converted into internal logic level by the interface and sent to the transmission part. The data is modulated into the signal required by the line by the modulation circuit and sent to the line. The receiving part receives the signal from the line, which is converted into digital signal after filtering, anti modulation and level conversion, and then sent to the digital terminal equipment.
