Spänningssignal

Spänningssignal is a Swedish term that translates to "voltage signal" in English. It refers to an electrical signal whose magnitude represents the value of a physical quantity. In electronics and instrumentation, a voltage signal is a fundamental way of conveying information. The voltage level can vary over time, encoding data such as temperature, pressure, light intensity, or audio.

These signals are generated by transducers, which convert physical phenomena into electrical voltage. For example, a thermocouple generates a voltage proportional to temperature, and a microphone converts sound waves into a varying voltage. The characteristics of a voltage signal include its amplitude, which indicates the strength or intensity of the measured quantity, and its frequency or waveform, which can represent other aspects of the signal.

Voltage signals are widely used in analog systems. They can be transmitted through wires and processed by various electronic components like amplifiers, filters, and analog-to-digital converters (ADCs). The precision and accuracy of a measurement often depend on the quality and stability of the voltage signal and the circuitry used to process it. Understanding voltage signals is crucial for designing, analyzing, and troubleshooting electronic circuits and measurement systems.
