avskärningsfrekvenser
Avskärningsfrekvenser, or cutoff frequencies, are fundamental concepts in signal processing and filter design. They represent the boundary frequency at which the power or amplitude of a signal is reduced by a specific amount, typically by half or to a certain decibel level. In analog and digital filters, the cutoff frequency defines the transition between the passband, where signals are allowed to pass with minimal attenuation, and the stopband, where signals are significantly attenuated.
There are different ways to define cutoff frequencies. The most common definition is the -3 dB cutoff
The specific cutoff frequency is a critical parameter that determines the behavior and application of a filter.
