Jonathan Bollinger Randall Robert Experiment 1 - Combinational Logic Circuits Part A: Design and build a 4-input majority circuit using AND, OR, and NOT gates. Digital Inputs: Data Inputs: Select Lines: None Clock: None Digital Outputs: Z Truth Table: A B C D Z 0 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1 1 0 0 1 0 0 0 0 1 0 1 0 0 1 1 0 0 0 1 1 1 1 1 0 0 0 0 1 0 0 1 0 1 0 1 0 0 1 0 1 1 1 1 1 0 0 0 1 1 0 1 1 1 1 1 0 1 1 1 1 1 1 Karnaugh Maps: None needed since output equation is easily derived from truth table. Equations: Z = BCD + ACD + ABD + ABC + ABCD Z = CD(A+B) + AB(C+D) Logic Diagram: Control Inputs: None Power Inputs: Supply Pin # 14 Chip # 74LS - 11, 32 Ground Pin # 7 Chip # 74LS - 11, 32 Trace: Attached to back of lab report. Ouptut Table: Attached to back of lab report.
