Signaalipeegeldus, commonly translated as signal reflection, refers to the phenomenon where an electromagnetic signal bounces off a surface. This occurs when a signal encounters a change in impedance or a physical boundary. The reflected signal travels in a different direction from the incident signal, with the angle of reflection generally equal to the angle of incidence, similar to light reflecting off a mirror.

In telecommunications and electronics, signal reflection can be a significant factor affecting signal integrity. Reflections can lead to issues such as signal distortion, reduced power transfer, and increased noise. For example, in coaxial cables, impedance mismatches at connectors or splices can cause signals to reflect back towards the source. These reflections can interfere with the original signal, causing data errors or performance degradation.

Minimizing unwanted signal reflections is crucial in the design of electronic systems and transmission lines. Techniques used to reduce reflections include impedance matching, using proper termination resistors, and carefully designing connectors and circuit board layouts. Understanding and managing signal reflections is therefore a fundamental aspect of ensuring reliable signal transmission. The phenomenon is also relevant in fields like radar, where reflected signals are used to detect and locate objects.
