The give inputs A, B are fed to a 2-input NAND gate. Draw the output wave form of the gate.

Explanation

For the NAND gate, the Boolean expression is

`Y=bar(A.B)=bar(A)+bar(B)`
For the given wave from, we have the following values for A, B and Y.
For time `t lt t_(1), A=1, B=1 :. Y=0+0=0`
For `t_(1) "to" t_(2), A=0, B=0 :. y=1 + 1 = 1`
For `t_(2) "to" t_(3), A=0, B=1 :. y=1+0=1`
For `t_(3)"to" t_(4), A=1, B=0 :. y=0+1=1`
For `t_(4) "to" t_(5), A=1, B=1 :. y=0+0=0`
For `t_(5) "to" t_(6), A=0, B=0 :. y=1+1=1`
For `t_(7) "to" t_(6), S=0, B=1 :. y=1+0=1`
Thus, the wave form for output y is given by
