Take A and B input waveforms similar to that in Ex. Sketch the output waveform obtained from AND gate .

Explanation

For `t le t_(1), " " A = 0 , B = 0` , Hence Y = 0
For `t_(3)` to `t_(2) , " " A = 1 , B = 0` , Hence Y = 0
For `t_(2)` to `t_(3), " " A = 1 , B = 1 `, Hence Y = 1
For `t_(3)` to `t_(4), " " A = 0 , B = 1 ,` Hence Y = 0
For `t_(4)` to `t_(5) , " " A = 0 , B = 0`, Hence Y = 0
For `t_(5)` to `t_(6) , " "` A = 1 , B = 0 , Hence Y = 0
For `t gt t_(6) , " " A = 0 , B = 1 `, Hence Y = 0
Based on the above , the output waveform for AND gate can be drawn as given below .
