- 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
- Comparing with an analog signal assuming a continuous range of values, a digital signal assumes discrete values, usually two permitted values.
- What is the term that is used to describe the process of converting a signal from digital to analog？（） A: packetization B: quantization C: decoding D: sampling
- The P-I characteristic of LED is linear, so no matter whether it is modulated by analog signal or digital signal, no bias current is required. A: 正确 B: 错误
