The Nyquist theorem states that a signal with the bandwidth B can be completely reconstructed if 2B samples per second are used. The theorem further states that: Rmax=2B* Log M M為位元電位(0與1),所以,M=2 where Rmax is the maximum data rate and M is the discrete levels of signal. 如題意, the maximum data rate = 2 × 7000 log2 2 = 14,000bits/sec (bps).的取樣... 查看完整內容 |
