青书学堂: (问答题) 填写下列代码的奇偶校验位,现设为奇校验:
1 0 1 0 0 0 0 1
0 0 0 1 1 0 0 1
0 1 0 0 1 1 1 0
1 0 1 0 0 0 0 1
0 0 0 1 1 0 0 1
0 1 0 0 1 1 1 0
举一反三
- 异步串行传输系统中,字符格式为:1位起始位、8位数据位、1位奇偶校验位、2位停止位。若传输数据为36H,采用偶校验,字符格式为____。 A: 0 0 0 1 1 0 1 1 0 0 1 1 B: 0 0 1 1 0 1 1 0 0 0 1 1 C: 0 0 0 1 1 0 1 1 0 1 1 1 D: 0 0 1 1 0 1 1 0 0 1 1 1
- 编写程序,创建下列10*10的数组,数组边界全为1,里面全为0。 [[1 1 1 1 1 1 1 1 1 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 0 0 0 0 0 0 0 0 1] [1 1 1 1 1 1 1 1 1 1]]
- 对HDB3码-1000+100-1000-1+1000+1-1+1-100-1+1-1进行译码,结果是( )。 A: 1 0 0 0 1 0 0 1 0 0 0 0 1 0 0 0 0 1 1 0 0 0 0 1 1 B: 1 0 0 0 1 0 0 1 0 0 0 1 1 0 0 0 0 1 1 0 0 0 0 0 1 C: 1 0 1 0 1 0 0 1 0 0 0 0 1 1 0 0 0 1 1 0 0 0 0 1 1 D: 1 0 0 0 1 0 0 1 0 0 0 0 1 0 0 1 1 0 0 0 0 0 0 1 1
- 以下HDB3码中,哪些可以确定其中有误码 A: +1 0 0 0 -1 0 +1 -1 +1 0 0 +1 0 -1 +1 -1 0 0 -1 +1…… B: +1 0 0 -1 +1 0 0 0 +1 -1 0 0 -1 0 0 0 +1 0 0 +1 -1…… C: -1 0 0 0 -1 0 +1 0 0 0 +1 -1 +1 0 0 +1 0 0 -1 +1…… D: -1 0 +1 0 0 0 -1 +1 0 0 0 +1 -1 +1 -1 0 0 -1 +1 0 -1……
- 若采用奇校验,当信息位为10001101时,校验位应是();若采用偶校验,当信息位为10001001时,校验位应是()。 A: 1;1 B: 0;1 C: 1;0 D: 0;0
