Gain of low pass filter formula
A low-pass filter 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 optics, high-pass and low-pass may have different meanings, depending on whether referrin…

WebTo calculate the output voltage of a passive low pass filter at any frequency, the voltage divider rule is applied between the resistor and capacitor. So, the output voltage vout is given by. Vout = Vin * (Xc/Z) Where Xc =capacitive reactance Z = total Impedance of circuit Z = R + jXc Z = √ (R2 + Xc2) So Vout = Vin * (Xc/√ (R2 + Xc2)) Passive Low Pass Filter Gain at ƒc where “ n ” is the number of filter stages. So for a second-order passive low pass filter the gain at the corner frequency ƒc will be equal to 0.7071 x 0.7071 = 0.5Vin (-6dB), a third-order passive low pass filter will be equal to 0.353Vin (-9dB), fourth-order will be 0.25Vin (-12dB) and so on.
