- 4. What are the advantages of digital signals, comparedwith analog signals?
- Modem is only used to convert digital signals into analog signals and transmit them on the line.
- 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
- Modem is only used to convert digital signals into analog signals and transmit them on the line. A: 正确 B: 错误
- A voltage comparator can convert analog signals into digital signals. A: Correct B: Wrong
