fasefølger

Fasefølger, also known as phase followers, are a type of electronic device used to synchronize the phase of an output signal with that of an input signal. They are commonly employed in audio and video systems to ensure that signals remain in sync, which is crucial for maintaining the quality and coherence of the final output.

The primary function of a fasefølger is to adjust the phase of the output signal so that it matches the phase of the input signal. This is achieved through various methods, including phase detection and phase shifting. Phase detection involves comparing the phase of the input and output signals, while phase shifting adjusts the phase of the output signal accordingly.

Fasefølgere are widely used in professional audio and video equipment, such as mixers, amplifiers, and video processors. They help to eliminate phase-related issues, such as comb filtering and phase cancellation, which can degrade the quality of the audio or video signal. By ensuring that the signals remain in sync, fasefølgere contribute to the overall performance and reliability of the system.

In summary, fasefølgere are essential components in audio and video systems, providing phase synchronization to maintain signal quality and coherence. Their ability to adjust the phase of output signals based on input signals makes them invaluable tools in professional audio and video applications.
