Priority Encoder Design 4 to 2 priority encoder with valid signal 2. Design 16 to 4 priority encoder using the 4 to 2 PE you have just built. Hint For question 2, Use five 4 to 2 PE and two OR gates. 1. Answer Starting with the truth table: Notice: x is “don’t care” From the truth table we can define Y0 , Y1 and Valid. Y0 = X1X2‘ + X3 Y1 = X3 +X2 V = X0 + X1 + X2 + X3 2. Answer Next Question>>>
