I'm having a problem understanding what influences the dual function has on the original function output.
For example, if I have a self dual function - for the input 11 the function out put will be 1, and the output of the dual function will be the same.
Now for dual function - I saw on the Internet that the dual function always give the opposite output compare to the original function. Im pretty confused because if we look on the function A*B Then the dual function is A+B. now for the input A=1,B=1 they giving the same output.
Some one can explain me what dual function is beside changing the operators?
