- 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
- The A/D converter is used to convert the analog signals to digital signals. For an 8-bit A/D converter with a conversion speed of 1 ms and an analog input range of 0-5V, if a 3.3V analog signal is inputted, the digital signal output should be: A: 168 B: 3.3 C: 168.9 D: 3
- 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
