Which of the following is not a significant characteristic of a pulse?
- A Pulse amplitude
- B Pulse width
- C Pulse position
- D Pulse duration modulation
Answer & Solution
Correct Answer
(D) Pulse duration modulation
Step-by-step Solution
Detailed explanation
A pulse is inherently defined by its physical properties: its height (amplitude), how long it lasts (width or duration), and its timing (position). Pulse duration modulation is a communication technique used to encode information by varying a pulse, rather than being a basic…
