What is the effect of increasing output port insertion loss on the signal level?

• A. It increases signal strength
• B. It decreases the available signal power
• C. It maintains the original power level
• D. It may improve signal quality

Answer: (B)

Increasing output port insertion loss directly impacts the amount of signal that is transmitted through a system, which in turn affects the available signal power. Insertion loss refers to the loss of signal power resulting from the insertion of a device in a transmission line. When the insertion loss increases, it implies that more of the input signal is being lost due to factors such as resistance, impedance mismatch, or inefficient coupling at the output port. As a result, the available signal power decreases because less of the original signal power is transmitted successfully through the system. This reduction in signal power can lead to weaker signal levels at the output, affecting the overall performance of the system. Thus, it is clear that increasing the output port insertion loss results in a decrease in available signal power. This concept is essential for understanding how signal integrity is maintained in communication systems, and accordingly, option B is the correct answer.
