What is a common consequence of using a mismatch in the transmitter/receiver and coaxial cable?

Using a mismatch in the transmitter/receiver and coaxial cable commonly leads to a loss of signal strength. When there is an impedance mismatch, signal reflections occur when the transmitted signal encounters a change in impedance along the transmission line. This mismatch can result in certain portions of the signal being reflected back toward the transmitter rather than being transmitted efficiently through the coaxial cable.

Consequently, the amount of power delivered at the load (receiver) can be significantly reduced, causing the downstream devices or systems to receive a weaker signal. This phenomenon is particularly detrimental in communications systems, where maintaining a strong and clear signal is crucial for performance and reliability.

Signal strength loss can lead to degraded performance in various applications, including a reduction in the quality of the audio or video being transmitted, increased bit error rates in data communications, and a general decline in system efficacy.

By recognizing the impact of impedance mismatches on signal strength, technicians and engineers can take measures to ensure compatibility between transmitters, receivers, and the transmission medium to optimize system performance.
