Generally, an analog signal can be reconstructed more accurately with A: more quantization levels B: fewer quantization levels C: a higher sampling frequency D: a lower sampling frequency E: either answer (a) or (c)

Generally,<br/>an analog signal can be reconstructed more accurately with ( ) A: more<br/>quantization levels B: fewer<br/>quantization levels C: a<br/>higher sampling frequency D: a<br/>lower sampling frequency

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

_______ is the name of the process of converting from analog to digital. A: Modulation B: Optical recognition C: Demodulation D: Virtualization
