In the last tutorial designing Audio Induction Loop Communication System - Transmitter Design , I explained how to design transmitter circuit for audio communication using induction loop. In this part of the tutorial, I will explain how to design …
Here I will describe a n induction loop audio communication system that allows you to transmit and receive audio wirelessly across a specific area—such as a room, house, or around an easy chair—without relying on traditional radio frequency (RF) si…
Here I wanted to show how you can listen to AM radio station using simple power amplifier. This power amplifier is built using the popular LM386 audio amplifier IC. The circuit diagram of Power Amplifier for AM radio is shown below. You can conne…
Here I redesigned the class AB audio amplifier that I had posted many years ago. In the original design, the microphone signal had to fight against the relatively low resistance of the biasing network. This often resulted in a muffled sound, lost…
Designing an audio amplifier can be a rewarding experience, especially when you aim for a balance of performance and accessibility. My recent project involved creating a Class AB power amplifier with common-emitter (CE) output stages. This journey …
The quest for pristine audio quality often leads electronics enthusiasts down the path of amplifier design. My own journey into creating a robust and clear sound system has been an evolving process, starting from simpler configurations and culminat…
