Ylipäästösuodatin
Ylipäästösuodatin, known in English as a high-pass filter, is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The cutoff frequency is defined as the point where the output power is reduced by half, which corresponds to a voltage reduction of approximately 70.7%.
These filters are fundamental components in signal processing and have a wide range of applications. In audio
The simplest form of a ylipäästösuodatin can be constructed using passive components like resistors and capacitors
