• A input is shorted to ground (A = 0)
• A input is shorted to the +5 V (A = 1)
dce 3.4
2011
• If the output waveform from an OR gate is the
same as the waveform at one of its inputs, the
other input is being held permanently LOW
• If the output waveform from an OR gate is
always HIGH, one of its inputs is being held
permanently HIGH
dce 3.5
2011

produce a HIGH output from a five-input OR
gate?

pressure and the temperature exceed their
mãimum limits at the same time ???
dce 3.8
2011
• Draw the output waveform for the AND gate
dce 3.9
2011
• Suppose that you have an unkown 2-input gate
(AND or OR gate)
• What combination of input levels should you
apply to the gate’s inputs to determine which
type of gate it is?
