In my textbook it says this:
"Digital communication, which can withstand channel noise and distortion much better than analog as long as the noise and the distortion are within limits, is more rugged than analog communication. With analog messages, on the other hand, any distortion or noise, no matter how small, will distort the recevied signal."
Since a digital signal already has quantization error, wouldn't the distortion caused by noise in an analog signal be no worse than the quantization error in a digital signal which can withstand the same noise?
