What is the different between 4-to-2 encoder and 4-to-3 encoder?

4 to 2 Encoders codes four different information into two codes. whereas 4 to 3 codes four different information into three code.
They are always coded with special and secret keys with these keys (or steps) information can be regenerated from codes
==========================================
An encoder is supposed to have n output for the applied 2n inputs. Hence, only the first one is valid

What is the length of the shortest side of Δabc whose perimeter is 64 units if the ratio ab to bc is 4to3 and ac is 20 less than the sum of the lengths of sides ab and bc?
It is customer to use capital letters for the vertices of a triangle, and lower case letters for the sides, with a being opposite A etc. So AB is c and so on. Converting the letters in the problem to capitals, and using a for BC and so on, we have 3 linear equations in a, b, and c, namely a + b + c = 64 c = (4/3)a b = a + c - 20 Substituting the second equation into the third gives b = (7/3)a - 20 Substituting this and the second equation into the first gives a + (7/3)a - 20 + (4/3)a = 64 Simplifying, (14/3)a - 20 = 64 (14/3)a = 84 a = 18 b = 22 c = 24 The answer is 18
What pH of 4 is times more acidic as a pH of 7?
As the pH decreases, the solution becomes 10 times more acidic for each point. A solution of pH 4 is 10 times more acidic than a solution of pH 5. A solution of pH 3 is 10 times more acidic than a solution of pH 4. 10 x 10 = 100 A solution of pH 3 is 100 times more acidic than a solution of pH 5.
