How is transmitter used in fibre optic communication system?
Transmitter:
This consists of analog to digital interface (driver). There, the input signal is converted within binary form. In that case, the carrier light is modulating along with respect to the binary digits. The outcome of LED/Laser diode will be ‘ON’ while the bit is ‘1’ and ‘OFF’ when the bit is ‘0’. In this way, the analog signal gets transformed within optical signal.
Q Define: self inductance. The coefficient of self induction of a coil is numerically equivalent to the opposing emf induced in the coil when the rate of change of current thr
