標題[問題] about the difference of symbol rate and sample rate
時間Sun Dec 31 14:42:33 2006
An anolog signal is sampled at its Nyquist rate 1/T_s,and quantized using L
quantization levels.the derived digital signal is then transmitted on some c
hannel.
a) show that the time duration, T, of one bit of the transmitted binary enco
ded signal must satisfy T<=T_s/(log_{2}L)
b)when is the equality sign valid?
how to solve this problem?
what's the relation between the sampling duration( rate) and symbol duration
( rate) ?
