    a filter that passes frequencies below a certain value and attenuates frequencies above that value


  1. low-pass filter

    A low-pass filter is a type of electronic filter that allows signals with a frequency lower than a certain cutoff frequency to pass through and reduces the intensity of signals with frequencies higher than the cutoff frequency. It's designed to block high-frequency signals while allowing low-frequency signals to pass unhindered. It's often used in audio, digital, and wireless communications to eliminate unwanted or interfering signals.


  1. Low-pass filter

    A low-pass filter is a filter that passes low-frequency signals and attenuates signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies depending on specific filter design. It is sometimes called a high-cut filter, or treble cut filter in audio applications. A low-pass filter is the opposite of a high-pass filter. A band-pass filter is a combination of a low-pass and a high-pass. Low-pass filters exist in many different forms, including electronic circuits, anti-aliasing filters for conditioning signals prior to analog-to-digital conversion, digital filters for smoothing sets of data, acoustic barriers, blurring of images, and so on. The moving average operation used in fields such as finance is a particular kind of low-pass filter, and can be analyzed with the same signal processing techniques as are used for other low-pass filters. Low-pass filters provide a smoother form of a signal, removing the short-term fluctuations, and leaving the longer-term trend. An optical filter can correctly be called a low-pass filter, but conventionally is called a longpass filter, to avoid confusion.
