Generally speaking, digital transmission can get higher signal quality than analog transmission, because? A: The repeater can regenerate digital pulses to remove signal distortion, and the amplifier amplifies the analog signal as well as the analog signal distorted B: Digital signals are smaller than analog signals and are not prone to distortion C: Analog signals are continuous and are not prone to distortion D: Digital signal is easier to sample than analog signal
