Continue reading → Digital communication: It is the mode of communication which uses discrete signals to transmit the necessary information. Advantages of Digital communication over analog communication 1) Due to the advancement in the IC(Integrated Circuits) technology and high speed computers, Digital communication systems are simpler and cheaper compared to analog systems 2) Using data encryption only permitted [...]
Continue reading → Communication There are mainly two modes of communication 1) Digital communication 2) Analog communication Digital communication: It is the mode of communication which uses discrete signals to transmit the necessary information. Discrete signals are the signals which uses sampled values these are also called discontinuing signals but periodic in nature. Analog communication: It is the [...]

Hence the conductivity of semiconductors can be given in the range of 103 Siemens/cm to 10?8 S/cm.The invention of the semiconductors has created the revolution in the electronics field. All the electronic [...]

Electric source is your car’s battery or [...]
Continue reading → Strange but fact Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. The alternative to the sulfuric acid electrolyte is potato juice. Hencewe can use potato as electrolyte. After all a fresh [...]
Continue reading → Amplifier is an electronic device which is used to increse the amplitude of the signal. The input to the output relation of the amplifier is called transfer function . Transfer function= output of the amplifier / input of the amplifier. The magnitude of the transfer function is called as Gain of the amplifier. Classification: Amplifiers [...]
