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) ? --
