A product term containing all the input variables of the function in either complemented or uncomplemented form is called a minterm.A 2-variables function has 2 2 =4 possible minterms. If the inputs are A and B, then minterms are A’B’, A’B, AB’, AB. KiTTY is one of the world’s best telnet and SSH customers for Windows operating systems.
Minterm
I have worked on the terminal emulator “MacTerm” for over 20 years. I have added dozens of features, improved emulation accuracy, implemented smart preferences, and ported it across multiple OS transitions (different processors, entirely different OS technologies). Extra Stable: 33lbs/15kg max. Load Functionality: Its functional design allows it to be used in tripod or monopod mode. It's invertible central column also allows for super low shots and great Macro control. Unique Ball Head: Design with 3 lock knobs and 360 degree panoramic panning dial that allows photographers adjust angle freely and quickly. Built-in bubble levels help for precise.
A product term containing all the input variables of the function in either complemented or uncomplemented form is called a minterm. A 2-variables function has 22=4 possible minterms. If the inputs are A and B, then minterms are A’B’, A’B, AB’, AB. These products are called minterms or standard product or fundamental product. Each minterms are obtained by the AND operation of the inputs. The total minterms of a three input (A, B and C) functions are 23=8. This may be represented as m0, m1, m2, m3, m4, m5, m6, m7. These are also known as minterm canonical form. The minterms combinations are given bellow,
A | B | C | Minterm | Symbol |
0 | 0 | 0 | A’B’C’ | m0 |
0 | 0 | 1 | A’B’C | m1 |
0 | 1 | 0 | A’BC’ | m2 |
0 | 1 | 1 | A’BC | m3 |
1 | 0 | 0 | AB’C’ | m4 |
1 | 0 | 1 | AB’C | m5 |
1 | 1 | 0 | ABC’ | m6 |
1 | 1 | 1 | ABC | m7 |
Sum of Product
The sum of the minterms is known as sum of product. We can also express it into canonical form as below
Maxterm
A sum term containing all the input variables of the function in either complemented or uncomplemented form is called a maxterm. A 2-variables function has 22=4 possible maxterms. If the inputs are A and B, then maxterms are A’+B’, A’+B, A+B’, A+B. Each minterms are obtained by the OR operation of the inputs. The total maxterms of a three input (A, B and C) functions are 23=8. This may be represented as M0, M1, M2, M3, M4, M5, M6, M7. These are also known as maxterm canonical form. The minterms combinations are given bellow,
A | B | C | Minterm | Symbol |
0 | 0 | 0 | A’+B’+C’ | M0 |
0 | 0 | 1 | A’+B’+C | M1 |
0 | 1 | 0 | A’+B+C’ | M2 |
0 | 1 | 1 | A’+B+C | M3 |
1 | 0 | 0 | A+B’+C’ | M4 |
1 | 0 | 1 | A+B’+C | M5 |
1 | 1 | 0 | A+B+C’ | M6 |
1 | 1 | 1 | A+B+C | M7 |

N.B. From that table, we found that complement of each maxterm is equal to the corresponding minterm. For examples: A+B+C is a maxterm. Its complement is (A+B+C)’. Now (A+B+C)’=A’B’C’ (by using demorgan’s theorems).

The product of the maxterms is known as product of sum. We can also express it into canonical form as below
