vekselstrømssignal

Vekselstrømssignal is the Danish term for alternating current signal. It describes an electrical signal characterized by its continuously changing voltage or current, which periodically reverses direction. Unlike direct current (DC) signals, which flow in a single direction, AC signals oscillate.

The most common form of vekselstrømssignal is a sinusoidal wave, described by its amplitude, frequency, and phase. Amplitude refers to the maximum voltage or current reached during a cycle. Frequency indicates how many complete cycles occur per second, measured in Hertz (Hz). Phase describes the signal's position within its cycle at a given moment.

Vekselstrømssignaler are fundamental in many electronic and electrical systems. They are used for power transmission over long distances due to the ease of voltage transformation using transformers. In telecommunications, they carry information in the form of modulated waves. Audio signals, such as those produced by microphones or played through speakers, are also vekselstrømssignaler. Electronic circuits often process and manipulate these signals to perform various functions. The ability of AC signals to change magnitude and direction makes them versatile for a wide range of applications.
