In digital communication, what does 'number of signal levels' refer to?
In digital communication, what does 'number of signal levels' refer to?
- The number of data levels
- The number of bits per pulse
- The number of different voltage levels allowed in a signal (correct)
- The number of different voltage levels that actually represent data values
What is the relationship between bit rate, pulse rate, and the number of different signal elements?
What is the relationship between bit rate, pulse rate, and the number of different signal elements?
- Bit rate = Pulse rate × log2L (correct)
- Bit rate = Pulse rate - log2L
- Bit rate = Pulse rate + log2L
- Bit rate = Pulse rate ÷ log2L
