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.
