RECEIVER SECTION
(1) LIGHT DETECTOR or photodetector
-The electrical signals are then amplified
-and reshaped into original digital pulses by the
shaper
-If the input signals are computer signals, the signal
can be directly taken out from the output of the
shaper circuit
(5) DECODER
-It is a ADC (analog to digital converter).
-Converts digital signal into analog signals, such as
voice, video or computer data.
