两个点数的各种组合(无序)对的熵和平均信息量为()
A: 4.337bit/symbol
B: 4.517bit/symbol
C: 4.566bit/s
D: 5,231bit/symbol
A: 4.337bit/symbol
B: 4.517bit/symbol
C: 4.566bit/s
D: 5,231bit/symbol
举一反三
- There are 4 messages A,B,C and D, with probability 1/4, 1/8, 1/8 and 1/2 respectively. The occurrence of each message is independent of each other. Calculate the average information of each message A: 1.5 bit/symbol B: 2.5 bit/symbol C: 2 bit/symbol D: 1.75 bit/symbol
- The transmission rate of the binary digital transmission system is 2400B,then the transmission bit rate is ____;if the system is hexadecimal, with the same symbol rate, the transmission bit rate is ____. A: 2400 bit/s, 2400 bit/s B: 2400 bit/s, 4800 bit/s C: 2400 bit/s, 9600 bit/s D: 4800 bit/s, 9600 bit/s
- 二进制码元速率为1200B，其信息速率为（） A: 1200 bit/s B: 1200 bit C: 2400 bit/s D: 2400 bit
- 通常,信息的单位是( ) A: bit B: bit/s C: s D: bit/h•s
- 接上题，若每个码元能携带 3 bit 的信息量，则最高信息传输速率为bit/s
