WebMay 6, 2016 · Now let us briefly discuss filter order. Low-pass filters do not simply cut frequencies above a certain value; they "roll off" frequencies above a certain "knee". A "first order" filter rolls off at a rate of -6dB per octave. This means that the signal component at twice the knee frequency is diminished by 6 decibels. WebAlso, in a digital circuit, a low pass filter might be used to de-bounce an input from a momentary contact button pushed by a person, or even a relay closure connected to a counter-timer input. A low pass filter may be constructed from on resistor R and one capacitor C. The cut off frequency Fc is determined according to the formula: Fc= 1/2*Pi*C.

WebA low-pass filter (LPF) is an audio signal processor that removes unwanted frequencies from a signal above a determined cutoff frequency. It progressively filters out (attenuates) the high-end above its cutoff frequency while allowing the low-end to pass through, ideally without any changes. http://learningaboutelectronics.com/Articles/Low-pass-filter.php

WebBoth of the methods assume polynomial relationships with the difference that loess is more flexible also using higher degree polynomials, while cubic spline is always cubic (x^2).
