Utgångsfrekvens

Utgångsfrekvens, or output frequency, is a term commonly used in electrical engineering and signal processing to describe the rate at which signals are produced or transmitted by a system. It refers to the number of complete cycles of a waveform that a system emits per second, measured in hertz (Hz). The output frequency can differ from the input or reference frequency, depending on the function of the device or circuit.

In oscillators and signal generators, the utgångsfrekvens is the characteristic output that can be dialed, tuned, or programmatically set. For example, a quartz crystal oscillator designed to produce a 10 MHz carrier will have an output frequency of 10 MHz. In modulators or mixers, the output frequency can be the result of frequency translation, where an input tone is shifted up or down in frequency.

The precision of the utgångsfrekvens is critical for applications such as radio communications, digital clocking, and high‑frequency data transmission. Small deviations can lead to phase noise, timing jitter, or spectral purity issues. Techniques such as phase‑locked loops (PLL) or frequency‑locked loops (FLL) are employed to maintain the desired output frequency in the presence of environmental changes or component drift.

Because the term is Swedish, it is often encountered in documentation for Scandinavian hardware manufacturers or in Swedish‑language technical literature. It is analogous to the English terms “output frequency” or “carrier frequency” in the broader context of signal engineering.
