Bessel Filter

A Bessel filter is a type of electronic filter designed to smoothly block or allow certain frequencies, especially in audio and signal processing. It excels at preserving the natural shape of signals, such as the waveforms of sound or data, reducing distortion. This makes it ideal when maintaining the original timing and clarity of the signal is important. Unlike other filters that might cause ringing or smearing, a Bessel filter provides a gentle transition between passed and blocked frequencies, ensuring accurate, natural-sounding results in applications like audio equipment and communication systems.
