Theoretically, the ideal (i.e., perfect) low-pass filter is the sinc filter. The sinc function (normalized, hence the \(\pi\)’s, as is customary in signal processing), is defined as \[\mathrm{sinc}(x)=\frac{\sin(\pi x)}{\pi x}.\] The sinc filter is a scaled version of …

For example, with R at 100k Ohms and C at 1600 pF, the center frequency becomes: Fo = 1 / (2 * Pi * 100k * 1600 pF) Fo = 1kHz. For the band pass filter to work properly, the capacitor in the low frequency filter (C1) needs to be twice the value of the capacitors in the high frequency filter (C2 and C3).

So the part of the circuit composed of resistor R and capacitor C form the low pass filter. The formula for calculating the cutoff frequency is, frequency= 1/2πR 2 C= 1/2π (15KΩ) (47nF)= 225.8Hz≈ 226Hz. So we use a 15KΩ resistor with a 47nF capacitor to form this 226Hz cutoff frequency point.

Subwoofer Low Pass Filter using Transistors. The circuit diagram exhibits an active low-pass filter layout that can be assigned any preferred cut-off point, across a large range easily by computing a couple of magnitudes for four capacitors. The filter includes an RC -network and a pair of NPN/PNP BJTs.

The low pass filter can be made as follows: Input - Resistor - (Output) - Capacitor - Ground ; Low pass filters filter out signal with frequencies above the cutoff frequency (1/2πRC). Since the cutoff is strictly determined by R and C, choose the appropriate resistor and capacitor to cutoff frequencies where you want to
How to Build a Passive Bandpass Filter Circuit

So the low-pass filter allows all frequencies below 10KHz to be passed through and blocks or greatly attenuates all frequencies above this 10KHz point. It's just that the positions of the resistor and capacitor are swapped for high and low-pass filters. So we use a 16KΩ resistor and a 1nF capacitor to form the low-pass filter.

To build a low pass filter, the components we will use are a function generator, a 10nF ceramic capacitor, and a 1KΩ resistor. This is the schematic of the circuit we will build, shown below: The formula to find the frequency cutoff point of an RC circuit is, frequency= 1/2πRC.
