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.
Two travelling sinusoidal waves are described by the wave functions Y 1 = 55.00 sin [π (4.00 x - 1200 t )] Y 2 =55.00 sin [π (4.00 x - 1200 t - 0.250)] Where x ,
VELOCITY- TIME GRAPH: The graphs which represents the variation of velocity of an object with respect to time is known as velocity- time graph.
