Characteristic impedance refers to the opposition a signal faces as it travels through a transmission line such as a cable or wire.
It is a key factor in maintaining signal strength, speed, and clarity over long distances.
When impedance is properly matched, signals travel efficiently without reflection or loss.
Mismatch can cause distortion, power loss, or signal interference.
Example: Coaxial cables with a characteristic impedance of 50 ohms are commonly used in television broadcasting and internet communication.
