A low-pass filter (LPF) is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. A low-pass filter is the complement of a high-pass filter.
In the optical domain, high-pass and low-pass have the opposite meanings, with a "high-pass" filter (more commonly "long-pass") passing only longer wavelengths (lower frequencies), and vice-versa for "low-pass" (more commonly "short-pass").
Low-pass filters exist in many different forms, including electronic circuits such as a hiss filter used in audio, 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.
Filter designers will often use the low-pass form as a prototype filter. That is, a filter with unity bandwidth and impedance. The desired filter is obtained from the prototype by scaling for the desired bandwidth and impedance and transforming into the desired bandform (that is low-pass, high-pass, band-pass or band-stop).

Anybody know of any inexpensive camo netting that will last a while? I bought one of these Allen brand camo nets cuz they were on clearance at Walmart but they are thin like cloth, not heavy plastic and not burlap. They faded within a very short time due to UV from the sun and became just a...

I bought this in June 2020. I'm not completely sure how many rounds I put through it, maybe 200. I decided to go with a smaller EDC pistol and just picked up a P365, so no need to hold onto this one.
In June I paid $689. It's in great condition with little use. It comes with the 2 standard...

This saw was purchased new in 2018 and has seen few hours in that time, as huge tree removal is not my primary niche. It is currently situated with a 32” rollamatic light weight chainsaw bar that...
