Function Library BitView Manual V2.5.00 WAVECOM W-BV
Function:
Changes the bit stream according to the “Non Return To Zero Space” (NRZ-S) decoding scheme, where no
bit change represents a ‘1’ and a bit change represents a ‘0’.
Note: This function is identical to NRZ-I.
Bi-Phase-L (Manchester)
In: Bit stream
Out: Bit stream
Function:
Analyze the bit changes of the bit stream. A change from ‘1’ to ‘0’ represents a ‘1’ and a change from ‘0’
to ‘1’ represents a ‘0’. The bits are analyzed in pairs, i.e., the number of output bits is half the number of
input bits.
Bi-Phase-M
In: Bit stream
Out: Bit stream
Function:
In Bi-Phase-M encoding, a logical ‘1’ is represented by a pair of bits of opposite values (‘10’ or ‘01’). A
logical ‘0’ is represented by a pair of bits of the same values (‘00’ or ‘11’). The decoding procedure halves
the number of output bits.
Bi-Phase-S
In: Bit stream
Out: Bit stream
