- 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
- what is an analog signal? A: Analog signal is a continous values B: Analog signal is a discrete values C: Analog signal is sometimes continous,sometimes discrete
- The signal transmission portion of the analog video surveillance system is responsible for the upstream transmission of the video signal and the downstream transmission of the control signal. ( ) A: 正确 B: 错误
- Comparing with an analog signal assuming a continuous range of values, a digital signal assumes discrete values, usually two permitted values.
