Low-pass filter
A filter that allows low-frequency signals to pass while attenuating high-frequency signals, used to attenuate noise and high-frequency jitter, though it introduces phase lag.
Timeline (last 90 days)
A low-pass filter is an image processing operation that allows low-frequency signals to pass and suppresses high-frequency signals, appearing in the spatial domain as a weighted average over neighboring pixels.
In the digital domain, envelope detection is typically simulated by taking the absolute value of a signal and then applying a low-pass filter, which is equivalent to the combination of a diode and RC filter in an analog circuit.
