A low-pass filter is a filter whose attenuation of filtered signals increases as the frequency of these signals growths. In other words, the low pass filter is a circuit that provides an easy passage for low frequency signals and a difficult transition for high frequency signals. The simplest example of such the filter is an RC circuit (Resistor–Capacitor). Below you have a set for measuring and analyzing sinusoidal signals passed through the RC low-pass filter.
