QUESTION
(a) Consider the following digital bit stream 01001100 is to be encoded in:
i. NRZ-I ii. Pseudoternary iii. Manchester iv. Differential Manchester
Show the waveforms for each of the above-mentioned codes showing clearly the bit durations, signal levels and transitions where necessary.
(Assumptions: The signal level for NRZ-I for most recent preceding mark was positive; the signal level of the most recent preceding space was negative for Pseudoternary).
(b) A frame transmitter is using the generator polynomial x4 + x + 1 and that the header contains the above bit pattern: 10100110. Derive the transmitted CRC header checksum.
(c) Show how you could use a (11,7) block code to correct and detect a 1-bit error if say, the subsequent 1011000 bit pattern is received, while the original 1001000 bit pattern was transmitted.
Problem (a) The IEEE 802 series of standards describe both the Physical and Data Link layers of their respective technologies. Two important standards are 802.3 and 802.5, respect
IDS RESPONSE BEHAVIOR Once IDS detects an anomalous network situation, it has a number of options. IDS responses to external stimulation can be classified as active or passive.
