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) ...

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, ...

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 below is the sample of the circuit filter for Nifty for trading on 13th August, 2018, based on closing value of 10th August, 2018. (On 10th August, Nifty closed at 11,429.50) Index Circuit ...

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 ...

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 ...

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 ...
