“We will discuss the Class D amplifier and build a hardware prototype of the amplifier and test its performance. Audio technology has undergone remarkable evolution in recent decades, reshaping how we consume digital media. From classic tube amplifiers to modern …
“A small adjustable and multipurpose class A amplifier which can be used to pre amplify the signals before giving into power amplifiers. In this tutorial, we are designing an AC amplifier using operational amplifier. The basic amplifying action of the …
“In this project, we have designed an FM broadcasting transmitter system with a bandwidth of about 433MHz suitable for radio broadcasting. This is the simplest form of FM transmitter which has the capability of transferring broadcasted music or voice to …
“This is easy to build and very useful project for hobbyists and students to learn and create OPAMP-based projects. The project accommodates a single OPAMP in the MSOP8 package. The project provides the user with multiple choices and extensive …
“This time I will show you how to make a sensitive metal detector also capable of discriminating between ferrous and nonferrous materials. The sensitivity is satisfactory, given that it is a relatively simple device. This is a continuation of David …
“A device that theoretically measures the speed of anything in meters per second. My project is to design a device that measures the speed of anything. This device, which will measure in meters / seconds, is generally referred to as a …
“There is nothing more satisfying then building a circuit and having it work as you intended and nothing so infuriating at it failing and not knowing why! There’s usually a few main culprits that can cause a circuit to …
“We report a handheld, portable potentiostat with a user-friendly interface for electrochemical sensing using a wireless power supply. 1. Synopsis The development of reliable and low-cost electrochemical potentiostats is essential in the field of chemical sensors and biosensors. These potentiostats …
“We often see the LM741 circuit in many projects. Sure, You can do them. But… Will it is more fun if you understand how it works? Do not worry at all. I always try to work it easy for you …
“This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of the magnet …
