Thanks!!Input: A, B = octal digits (see representation below); Cin = binary digitOutput: S = octal digit (see representation below); Cout = binary digitTask: Using binary FAs, design a circuit that acts as an octal FA. More specifically, this circuit would input the two octal digits A, B, convert them into binary numbers, add them<\/li>\n<li><img decoding=\"async\" src=\"http:\/\/www.gravatar.com\/avatar\/1ab3e4ae1d407d371e13c9f629ddb62c?s=32&amp;d=identicon&amp;r=PG\" \/><br \/>\nuser225269<br \/>\nphp boolean-operations<br \/>\nI&#8217;ve notice that when one of the two conditions in a php if statement is not true.
