a pulse is applied to each input of a 2-input nand gate. one pulse goes high at t = 0 and goes back low at t = 1 ms. the other pulse goes high at t = 0.8 ms and goes back low at t = 3 ms. the output pulse can be described as follows:
a pulse is applied to each input of a 2-input nor gate. one pulse goes high at t = 0 and goes back low at t = 1 ms. the other pulse goes high at t = 0.8 ms and goes back low at t = 3 ms. the output pulse can be described as follows:
for a nor gate with 4 inputs, to get the output high, how many kinds of combinations are there in total?
which one is wrong in the follwing statement?
an inverter performs a not operation.
a not gate cannot have more than one input.
if any input to an or gate is zero, the output is zero.
if all inputs to an and gate are 1, the output is 0.
a nand gate can be considered as an and gate followed by a not gate.
a nor gate can be considered as an or gate followed by an inverter.
the output of an exclusive-or is 0 if the inputs are opposite.
two types of fixed-function logic integrated circuits are bipolar and nmos.
in fixed-function logic, the circuit cannot be altered.
dip is plug-in mounting
an and gate can have only two inputs.
a nand gate has an output that is opposite the output of an and gate.
for or gate, the output is high when any of the inputs is high.
an xor gate can have only two inputs.
the expression for a 4-input and gate can be x=abcd.
for a 2-input or gate, output x is high when either input a or input b is high.
the boolean addition 1 1=1 is right.
for a nand gate, when any of the inputs is low, the output will be high.
the boolean expression for the output of a 2-input nor gate can be written as .
soic package is much ller than dip.
the output is high when any of the inputs is high.
for 2-input or gate, the timing digaram is right.
the following timing diagram shows a xor gate.
the timing diagram below is a nor gate.
not gate also can be written as
typical ic gate packages are dip and
a&1=
for an nand with 3 inputs, when all the inputs are 1, the output is
continuously do the xor operation with 199 logic 1, the output is
if all the 3 inputs of a basic logic gate are 0, the output is 1, it should be gate.
