Low Pass Filter

A low-pass filter is a filter that passes low frequency  signals  but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. It is sometimes called a high-cut filter, or treble cut filter when used in audio applications.

A filter network that passes all frequencies below a specified frequency with little or no loss , but strongly attenuates higher frequencies. (188 )

<electronics, graphics> A filter that attenuates high frequency components of a signal.
In image processing, a low pass filter might be used to remove noise from an image.
