Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a 4-to-1 multiplexer for the Boolean function f(A,B,C)=Σ(0,1,2,3). Provide the truth table and a circuit diagram.

💡 Hint: Construct the truth table for the minterms and figure out the connections.

Challenge 2 Hard

Using a flip-flop counter, illustrate how an 8-to-1 multiplexer could convert parallel 8-bit data to serial data flow.

💡 Hint: Document the operation of selection lines as the counter advances through the clock cycle.
