What is the full form of PPM?(a) pulse-position modulation(b) position-pulse modulation(c) pulse-pulse modulation(d) position-position modulationThis question was posed to me at a job interview.I'd like to ask this question from Single Side Band Transmission in chapter SSB Modulation of Analog Communications

Answer»

The correct choice is (a) pulse-position modulation

Easy explanation: PPM is used for both analog and digital signals. In PPM, when a single pulse is transmitted in the ALLOTTED time shift, the message bits GET encoded. It is mostly used for optical COMMUNICATION such as OPTIC FIBER.
