i. Noise can be seen as enemy in communication, By what means can you prove that Thermal noise is often refered to as white noise and why. ii. How does short noise occur in semiconductors? ji. Calculate the reverse saturation current(amps) where 1², = 20m amps Ipc = 4x 10-3 amps 9. = 1.6 x 10-19 B =3.4KHZ. iv. By a suitable graphical representation sketch signal voltage (V) against period (t) of an FM System at t ranges from 1second to 12 seconds. Taken magnitude of signal voltage to be 10V, 2nfc = 10 x 10°, 2fm = 3000, carrier deviation is 2.337KHZ You are required to show work
