Designing a filter circuit is straightforward with the combination of a resistor and a capacitor or an inductor, referred to as RC or RL filters respectively.

A filter circuit consists of passive components (resistors, capacitors, and inductors) and sometimes active components (op-amps, transistors, or ICs) ...

Band Pass Filter Circuit. As told earlier we will discuss the Passive Bandpass Filter which is constructed using resistor and capacitor. It is a combination of the high pass filter and low pass filter ...

This subwoofer active filter circuit is a 24 dB octave filter with a Bessel character and cutoff frequency of 200 Hz. So, if you are interested in experimenting with audio circuits in subwoofer range, ...

In the previous article, we discussed the basics of impedance matching and how to use an impedance matching transformer.Apart from using an impedance matching transformer, designers can also use ...

This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and ...

The circuit is used to capture this frequency range and reject those which are not within the range. To do this, two active second class filters were used for critical damping of signals. The first ...

Given a major overhaul in Live 12.2, Auto Filter features a variety of creative filter types, new modulation options and real ...

My revised filter circuit with off-the-shelf component values. So each of the components in the above schematic needs moving up or down a little way to a preferred value.
