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

Which is the modulation and demodulation technology mainly used among the following communication modes? A: Analog channel transmits digital data B: Analog channel transmit analog data C: Digital channel transmit digital data D: Digital channel transmit analog data
