What is V in logic gates?
The Sum-of-Products (SOP) Form When two or more product terms are summed by Boolean addition, the resulting expression is a sum-of-products (SOP).
Some examples are: AB + ABC ABC + CDE +BCD AB+ BCD + AC Also, an SOP expression can contain a single-variable term, as in A + ABC + BCD.What is the standard sop expression?
DeMorgan's law tells us that not A and not B is the same thing as not (A or B) so the logic gate you're looking for is the nor gate.
How do you make a truth table from a Boolean expression?
The voltage used with these circuits is usually 5V.
Initially we will treat 5V as logic 1 and 0V as logic 0.
In practice there needs to be some tolerance on these nominal voltage levels.
The tolerance levels depend on the type of logic circuit being used, but an example would be 0 – 0.
8) V = “0” & 2 – 5V = “1”.
