In this post I will comprehensively discuss 10 different types of active filter circuits which can be used for filtering music and audio with the desired levels of bass and treble effects. We also learn about their working, types, characteristics, and practical applications circuits. Contributed By: Ken Madison In audio signal processing circuits, filters are used […]

22 Watt Stereo Amplifier Circuit using TDA1554
The IC TDA1554 based Amplifier circuit discussed in this article can provide up to 22 watts per channel into a couple of four-ohm loudspeakers. The main attraction is that you can construct it for less than $15. This implies that you may make a power amplifier for your car’s front speakers, another for the back […]
Robot Voice Generator Circuit
A robot voice generator circuit is a device which modifies a normal human voice into a typical robot like voice, that we normally come across in movies, or video games. The working concept of the circuit is actually simple. The actual human voice signal is subjected to an external frequency modulation signal, such that the […]
Simple Hum Filter Circuit for Amplifiers
The following post discusses a simple hum filter circuit which can be installed between an audio input source and a power amplifier, so that any possible mains hum frequency within the audio signal is blocked and only the clean audio frequency is allowed to go through. Introduction As the name suggests, hum noise is in […]
Build this Subwoofer Amplifier Circuit [Mini Ground-Shaker]
A subwoofer amplifier is basically a power amplifier designed to filter and extract the low frequency content from the input audio signal and amplify it to the desired levels. This allows a sound reproduction that is enhanced with deeper bass, generating a concert hall like, or an immersive theater like sound effects. By: Sania D’souza […]
Types of Power Amplifier Classes Explained in Simple Words
In this post I am going to explain power amplifiers and their classification according to their output electrical characters and application. We will be exploring amplifier classes: A, B, AB, C, D, E, F, G, H, I, S and T briefly and yes, that’s a lot of amplifier types that are available in today’s electrical […]
