the line-coded signal can be used to turn on and off a light source in free-space optical communication, most commonly used in an infrared remote control. the line-coded signal can be printed on paper to create a bar code. the line-coded signal can be converted to magnetized spots on a hard drive or tape drive.
The binary signal is encoded using rectangular pulse-amplitude modulation with polar return-to-zero code. Return-to-zero (RZ or RTZ) describes a line code used in telecommunications signals in which the signal drops (returns) to zero between pulses. This takes place even if a number of consecutive 0s or 1s occur in the signal. The signal is ...
Carrier-Suppressed Return-to-Zero (CSRZ) is an optical line code.In CSRZ the field intensity drops to zero between consecutive bits (), and the field phase alternates by π radians between neighbouring bits, so that if the phase of the signal is e.g. 0 in even bits (bit number 2n), the phase in odd bit slots (bit number 2n+1) will be π, the phase alternation amplitude.
The reason why bipolar encoding is classified as a return to zero (RZ) is that when a bipolar encoded channel is idle the line is held at a constant "zero" level, and when it is transmitting bits the line is either in a +V or -V state corresponding to the binary bit being transmitted. Thus, the line always returns to the "zero" level to denote ...
This line code is called bipolar with three-zero substitution (B3ZS), and is very similar to HDB3. Each run of 3 consecutive zeros is replaced by " 00V " or " B0V ". The choice is made to ensure that consecutive violations are of differing polarity, i.e. separated by an odd number of normal B marks.
