A power amplifier circuit is the one with minimum output impedance, used to drive loads like a speaker, which require high power at low impedance.

A power amplifier circuit using MOSFET has been designed to produce 100W output to drive a load of about 8 Ohms.  The power amplifier circuit

Here we are building a wireless FM transmitter which uses RF communication to transmit the medium or low power FM signal. The maximum range of

Air flow detection is often necessary in many applications or systems where it is necessary to detect the presence of air to have a descriptive

Mosquito repellents like coils, mats, liquid vaporisers, creams are often used at various places. However they are prone to be fatal and can cause harm

The circuit which we have explained below is used to generate the output voltage whose magnitude is just double of the supplied input voltage. In

The circuit presented here is used to change the tune/melody into a different pitch level by devoid of loss in the tune. The characteristics of

This circuit helps you to manage your appliances in your home devoid of getting off from your bed. All you need is to just clap

During our journey through train and bus, we carry many important things and all the time we have fear that someone might lift our luggage.

Logic gates are basically are group of three basic logic gates specifically called as NOT , AND and OR gate. All the gates have their
