Binary-coded decimal (BCD) to binary converter: Design a logic circuit that functions to convert a 2-digit BCD (8 bits) to an 8-bit binary number. Note that the number your circuit handles is between -99 and 99. Draw a logic circuit that attempts to accept 2 signed integers A and B, a control signal Z which is set to 0 for addition and 1 for subtraction, and outputs the result as an 8-bit binary number in 2's complement representation. You may use 8-bit adders and multipliers with two 4-bit inputs and one 8-bit output.
