Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is: 3) Phase
Explanation:
In differential encoding, the phase difference between successive signal elements is used to encode the data. This technique is often used in digital modulation schemes like Differential Phase Shift Keying (DPSK), where information is represented by changes in phase rather than absolute phase values.
-
It does not depend on magnitude, frequency, or period, but on how the phase changes from one symbol to the next.
Hence, the blank should be filled with phase
