The high-pass filter is designed using a capacitor (“C1” in the circuit diagram) of 100 nF and a resistor (“R2”) of 3.2 kilo-ohms. Using these values for the capacitor and resistor, the cut-off frequency of the filter can be calculated as follows: FH= 1/ (2πR2C1) FH= 1/ (2π*3.2k*100n) FH= 500Hz (approx.)

An audio filter circuit is a broadband filter and is also called a wide bandpass filter because its bandwidth is restricted to the audio frequency. Audio filter circuit can be formed by simple cascading high pass filter circuit and low pass filter circuit and is generally the choice for simplicity of design and performance through such a circuit can be realized by a number of the …

As proposed, to design a high-pass filter circuit quickly, the following formulas and the subsequent steps can be used for calculating the relevant resistors and capacitors. First, select an appropriate value arbitrarily for C1 or C2, both can be identical. Next, calculate R1 by using the following formula: R1 = 1 / √2 x π x C1 x Frequency

Audio filters are the electronic circuits designed to amplify or attenuate a certain range of frequency components. They serve as a unique type of amplifier or a passive circuit with frequency-dependent outputs. Essentially, they help eliminate any unwanted noise from an audio signal, improving the tone of the output.
