Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a set of active inputs for a priority encoder with eight inputs, write the Boolean expressions for the outputs A, B, and C.

💡 Hint: Begin with identifying active inputs and their corresponding binary values.

Challenge 2 Hard

Design a priority encoder circuit with four active inputs, ensuring a proper schematic.

💡 Hint: Map out the truth table first, then translate it into a logical schematic.
