Modulation
Importance & Reasons
-
Operating Range
Higher frequency signals have more energy, allowing longer-distance transmission.
-
Mutual Interference
Modulation enables multiple signals to share the medium without interference by allocating different frequency bands.
Types
-
-
Phase Modulation (PM)
-
Formula: 
-
Example: Used in satellite communications, some Wi-Fi protocols.
Definition
This allows the transmission of signals over longer distances and helps to avoid interference between multiple signals.
Purpose
To shift an information-bearing low-frequency signal to a higher-frequency carrier for effective transmission.
