Question

Sketch the output Y from a NAND gate having inputs A and B given below `:`

Answer 1

For `tle t_(1), A = 1 ,B=1 ,` Hence Y = 0
For`t_(1)` to `t_(2), A =0,B = 0, ` Hence Y = 1
For`t_(2) ` to `t_(3), A =0, B = 1 , ` Hence Y = 1
For `t_(3) ` to `t_(4), A= 1 , B= 0 , ` Hence Y = 1
For `t_(4) `to `t_(5), A= 1, B= 1 , ` Hence Y = 0
For `t_(5)` to `t_(6), A = 0 , B= 0 , `Hence `Y = 1 `
For `t gt t_(6), A =0 , B = 1 , ` Hence Y=1
