Is the LPF’s Cutoff Frequency Always the Point of 3dB Attenuation? Exploring the Relationship
The cutoff frequency of a low-pass filter (LPF) is a crucial parameter that determines the filter’s ability to pass low-frequency signals while blocking high-frequency signals. While the cutoff frequency is often defined as the point where the signal power is reduced by 3 decibels (dB) compared to its power at lower frequencies, the relationship between … Read more
