LED Physics and LED Science Explained Briefly by Article

As per LED Chemistry, Silicon Germanium bandgap semiconductor materials are not suitable for LED because the very higher percentage of electrical energy is to be converted into thermal energy hence emission of light is negligible.In silicon germanium semiconductor diodes electrons and holes recombined non-radiative radiation.Since

Digital Electronics Basics and Digital Signal Fundamentals

Before the study, of Digital Electronics, We need to know Analog Signal was represented by a periodic sinusoidal wave.There is nothing any discontinuous point exists, meaning absolutely continuous with respect to time. Now creating a discrete point with same unit time interval on continuous analog

Analog Devices Basic and Analog Signal Fundamentals

Before the study of the analog devices, we would need to study the characteristics of the analog signal.Information which is to be converted into the electrical form of signals and suitable for transmission by using analog devices from one place to other is called Signal. There
