Besides, how many rows are in a truth table with 4 variables?
sixteen rows
Secondly, how many rows should an AND gate have in the truth table? Any logic block with n inputs will have a row in its Karnaugh mapping (formal name for Truth Table) for every possible combination of input states. That is, it will have 2^n rows.
Secondly, how many rows are there in 3 input gate truth table?
There is always at least one output column (on the right side) that represents the result of all possible combinations of the inputs. For Example: In the following truth table there are 3 input columns, then we will have 23= 8 combinations (8 rows).
How many rows are there in a truth table with n propositional variables?
Note that a truth table for a function of N variables has 2^N rows.
