4. ### Recursive implementation of combinational logic

Hello Everyone! I'm trying to implement a recursive implementation of the following function **We are allowed to use also $Multiplexer(2^n : 1)$ gates. If anyone has any idea and wants to share it I'd be glad to hear :) Have a great day!
5. ### Digital Electronics

Depending on the choice of choice for a logic circuit, 4-bit input (N), connected, given three is doing one of the operations. a) F = 4N + X b) F = MOD (N, X) c) F = ABS (2N - 3X + 5) * MOD is modulo operation. ** ABS is absolute value operation. *** The value of X is accepted as 2 if the son of...
