határfrekvenciája
Határfrekvenciája, often translated as cutoff frequency, is a fundamental concept in signal processing and electronics. It refers to the frequency at which a system, such as a filter or an amplifier, transitions from allowing signals to pass through largely unattenuated to significantly attenuating them. In simpler terms, it's the dividing line between frequencies that are "passed" and frequencies that are "blocked."
The exact definition and behavior around the cutoff frequency can vary depending on the type of filter.
The cutoff frequency is typically defined as the frequency at which the power of the signal is
