If you were to measure a digital signal with an oscilloscope and it displayed 3 signal levels, what can you say about that signal with respect to encoding?Question 6Answera.Pseudoternary Encodingb.Differential Manchester Encodingc.NRZ-L Encodingd.FSK Modulation
Solution
The digital signal displaying 3 signal levels on an oscilloscope indicates that it is using a form of multilevel encoding. However, none of the options provided (Pseudoternary Encoding, Differential Manchester Encoding, NRZ-L Encoding, FSK Modulation) typically use 3 signal levels.
a. Pseudoternary Encoding uses two levels. b. Differential Manchester Encoding also uses two levels. c. NRZ-L Encoding uses two levels. d. FSK Modulation is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal, but it doesn't necessarily imply three levels.
Therefore, based on the options provided, none of them would typically display 3 signal levels. It's possible that the signal could be using a different form of encoding not listed in the options.
