Enkeländsignalning

Enkeländsignalning, often translated as single-ended signaling, is an electrical signaling method where information is transmitted using a single conductor. This conductor carries the signal voltage relative to a common reference potential, typically ground. In contrast, differential signaling uses two conductors, with the signal represented by the voltage difference between them.

The primary advantage of enkeländsignalning is its simplicity and reduced component count. It requires fewer wires and simpler transmitter and receiver circuits, making it cost-effective for many applications. This simplicity also contributes to a smaller physical footprint.

However, enkeländsignalning is more susceptible to noise and interference. External electromagnetic disturbances can easily affect the signal on the single conductor, leading to data corruption. The common reference, usually ground, can also be a source of noise pickup. Furthermore, signal integrity can degrade over longer distances due to impedance mismatches and signal reflections, which are more problematic than in differential signaling.

Despite these limitations, enkeländsignalning remains widely used in many contexts. It is common in low-speed digital interfaces, analog sensor readings where noise is manageable, and within integrated circuits where distances are short and shielding can be implemented effectively. Examples include simple serial communication protocols and connections within consumer electronics. The choice between enkeländsignalning and differential signaling depends heavily on the specific application requirements, including speed, distance, noise environment, and cost constraints.
