GATE Questions on Digital Logic
I need GATE Questions on Digital Logic so I am looking for it in net since four hours but couldn’t get any site. Can you help me in this regard? Mention me sites providing questions and answers on Digital Logic Gates with explanation.

Re: GATE Questions on Digital Logic Here is some Digital Logic question papers: 1. On pages 226227 of the textbook, questions: 3, 5, 8, 9, 11. #3. Use a truth table to show that X = (X AND Y) OR (X AND NOT Y) X Y  (X AND Y) OR (X AND NOT Y) 0 0  0 0 1  0 1 0  1 1 1  1 Notice that in the truth table, the value of (X AND Y) OR (X AND NOT Y) always has the value of X. #5. Show and the AND function can be constructed from two NAND gates. Since (A AND B) is equivalent to (NOT (NOT (A AND B)), you can construct AND by 2. Build a decoder with three input lines but with only six output lines. If the value of the input corresponds to 6 or 7, then all output lines should be asserted to signal an error. This is just like an ordinary 3input, 8output decoder, except that if the input1 and input2 are both 1 (resulting in an input value of 6 or 7), all the outputs should be 1. This is accomplished by ANDing input1 and input2 and then sending that result to be OR’d with the normal value for each output. See below. Complete question paper is available in pdf file which have uploaded here. Feel free to download this question paper.
