Task 2: BCD Detector Design and build a circuit in which the input is 4 bits and the output indicates if the input is an invalid BCD number (specifically, 8421 BCD): Set (= ' 1 ') for invalid BCD Reset ' 0 ') for valid BCD In report: Describe the problem All of these foundational components of the design: Variable definition Truth table Karnaugh Map that identifies simplest SOP equation (hint: not all input bits are needed!) Logic circuit Chip schematic circuit (remember that we only have 2-input chips) I need help with Logic circuit and Chip Schematic
