几种编码方式
- A. 产生一个长为1000的二进制随机序列,“0”的概率为0.8,”1”的概率为0.2;B. 对上述数据进行归零AMI编码,脉冲宽度为符号宽度的50%,波形采样率为符号率的8倍,画出前20个符号对应的波形(同时给出前20位信源序列);C. 改用HDB3码,画出前20个符号对应的波形;D. 改用密勒码,画出前20个符号对应的波形;E. 分别对上述1000个符号的波形进行功率谱估计,画出功率谱;F. 改变信源“0”的概率,观察AMI码的功率谱变化情况;-have a length of 1,000

rs485
- 操作串口直接进行RS485多机通信的类。单片机下485多机通信很容易,用UART的Bit9即可,Windows下就麻烦得多,Windows下串口Bit9用作奇偶校验,要切换Bit9就要动态改通信格式,而且切换时间要跟得上单片机的us级时间。这个自己写的Class用独立线程、Windows高精度定时器机制,高速切换Bit9,示波器测量,时间在10us左右,已用于门禁系统多年,长时间运行可靠! -Direct RS485 serial port operation multi-machine c

USBkey
- 用单片机做的USB开发板的键盘程序 开发板上共有8个按键,功能分别为: K1:左Ctrl键 K2:左Shift键 K3:左Alt键 K4:0键 K5:1键 K6:2键 K7:Caps Lock键 K8:Num Lock键 按键功能测试: 同时按下K1和K2可做输入法切换,这跟键盘上的两个键功能一样的。 K7可打开大写字母锁定,同时LED2亮起。K8是小数字键盘锁定键, 当数字键盘打开时,LED1亮起,这时可用K4,K5,K6输入数字。 请留意EDN板
