Total active reflection coefficient

Imagine you are playing basketball with your friends and you throw the ball against the wall. When the ball hits the wall, it bounces back to you. That's what we call reflection.

In the same way, when we send a signal through a cable or a wire, a portion of that signal gets reflected back towards the source. This can have a negative impact on the quality of the signal.

To measure how much of the signal has been reflected back, we use something called the total active reflection coefficient. This coefficient tells us the ratio between the reflected signal and the original signal that was sent.

Think of it as a way to tell how much of the ball's energy comes back to you when you bounce it against the wall. If the ball bounces back with the same amount of energy, then it means there was no loss in the reflection. Similarly, if the total active reflection coefficient is zero, it means there was no reflection and all of the signal was transmitted successfully.

So, in summary, the total active reflection coefficient is a measure of how much of a signal sent through a cable or wire was reflected back towards the source. It can help us determine the quality of the transmission and identify any potential issues.
