Explain how receiver functions in fibre optic communication system.
Receiver:
The optical signal received must be first converted within digital form and in case analog output. Moreover, the analog output has to be amplified to overcome the loss when any throughout its propagation via optical fibre.
Assume we place a screen with two parallel slits right in front of a lens (with focal distance f ), and illuminate with light (at wavelength λ) from far away. (a) What will be the
It is significant to denote the time interval to in which we are talking about average. In a given time interval t 1 to t 2 the average angular acceleration is defined as ,
Coulomb's law (C. de Coulomb) The primary law for electrostatics is analogues to Newton's law of universal gravitation. This states that the force among two point charges is p
Basic concepts of electromagnetic spectrum: BASIC CONCEPTS 1. When Sun light falls on a prism, the transmitted light produces a sequence of colours called 'Spectrum'. 2
Earth is losoing heat in order balance the input outpout . But where is going that heat since there is nothing out to get it. Billions of stars are loosing heat the same way and so
