Passive Filter Circuits : 4 Steps - Instructables

The high pass filter can be made as follows: Input - Capacitor - (Output) - Resistor - Ground High pass filters filter out signal with frequencies below 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

Plug the completed filter in line with your audio device. audio device --> audio cable --> RC Filter --> audio cable --> speakers or recording device Turn on your speaker and see how the filter works! If you are still getting noise, you can play around with different values on your components.

Passive LC filters can be quite effective in improving the audio from a receiver. Residual power supply hum can be virtually eliminated and background hiss originating from wideband high-gain amplifier stages is often greatly reduced.
How to Build a Passive Bandpass Filter Circuit

The high-pass filter design creates the lower cutoff frequency point. In the circuit, we want the lower cutoff frequency point to be 1KHz. Therefore, the high-pass filter passes all frequencies above 1KHz. The formula for calculating the lower cutoff frequency is, frequency= 1/2πR1C1= 1/2π (150Ω) (1μF)= 1061 Hz≈ 1KHz.

Here is the schematic to build a 60Hz notch filter: Figure 8. Notch filter This also is a classic twin t filter. There is a low frequency filter (R2, R3, and C1) and a high frequency filter (C2, C3, and R5). The two filters act together to exclude only a narrow band of frequencies.
Low Pass Filter - Passive RC Filter Tutorial
https://www.electronics-tutorials.ws/filter/filter_2.html
Passive filters are made up of passive components such as resistors, capacitors and inductors and have no amplifying elements (transistors, op-amps, etc) so have no signal gain, therefore their output level is always less than the input.

The input signal from the passive, high-pass filter is connected to the IC’s non-inverting input pin (pin 3). A 22 kilo-ohm resistor (“R5” in the circuit diagram) is connected between the IC’s pins 6 and 2, providing negative feedback. The inverting pin (pin 2) is grounded via a …

Uses for passive filters. Filters are widely used to give circuits such as amplifiers, oscillators and power supply circuits the required frequency characteristic. Some examples are given below. They use combinations of R, L and C As described in Module 6, Inductors and Capacitors react to changes in frequency in opposite ways.
