Question
Discuss the compatibility of a ITU-T V. 26 modem employing a pattern $A$ phase change with a similar modem using the pattern B phase change.
Step 1
26 modem is ITU-T V.26 is a standard for a 2400 bits per second modem operating on four-wire leased telephone circuits. This modem uses phase modulation (specifically, Differential Phase Shift Keying or DPSK) to transmit data. Step 2: Identify the patterns A and B Show more…

Consider a data sequence 1 0 0 0 0 0 0 0 0 1 0 1 that is transmitted at a rate of 5 kb/s. The sequence is to be transmitted using NRZ-L, B8ZS, Manchester, AMI, polar RZ, NRZ-I, and differential Manchester techniques. a- Draw the waveform for each scheme. b- Which scheme is being used in LAN? c- Determine the bandwidth for each scheme. d- Which schemes cannot use AC coupling? e- Which schemes have self-synchronization capability?
