the two inputs to and gate are 4V and 5V.if threshold
voltage is 0.5V.then what is output of and gate?if input
voltage is reduced to 0.52V each,then what will be output?

Answer Posted / mayank gupta

The output Voltage is high that is 5V if the input to the gate is 4V and 5V and the supply voltage of the gate is 5V. Now if
each voltage is decreased by .52V then the 4v volt output will become 3.48V which is the undefined state for a Gate. Hence, the output cannot be predicted. If it reads it as low then the output will be lying between 0-0.8V and considered as low. If it reads high then the output will between 4.5-5V considered as high.

Alok and Bhanu play the following min-max game. Given the expression N = 9 + X + Y - Z Where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be 27 0.0 20 18
