An even-parity generator takes 4 data bits D3 D2 D1 D0 = 1011. What parity bit P does it produce? / Even-parity generator 4 data bits D3 D2 D1 D0 = 1011 लेता है। वह कौन-सा parity bit P उत्पन्न करेगा?
1.
0 / 0
2.
1, because the data already has even parity / 1, क्योंकि data में पहले से even parity है
3.
0, because P equals the XOR of the bits only for odd parity / 0, क्योंकि P, bits के XOR के बराबर केवल odd parity हेतु होता है
4.
1 / 1
Correct Answer: 1 / 1
The data 1011 contains three 1s (odd); for even parity the parity bit must be 1 so that the total number of 1s becomes four. Equivalently, P = D3 ⊕ D2 ⊕ D1 ⊕ D0 = 1. / Data 1011 में तीन 1s हैं (विषम); even parity हेतु parity bit 1 होना चाहिए ताकि 1s की कुल संख्या चार हो जाए। अर्थात P = D3 ⊕ D2 ⊕ D1 ⊕ D0 = 1।
