Скачать или смотреть Digital Logic Class 17: Higher-Order Decoder using Lower-Order & Priority Encoder Explained

In Digital Logic Class 17, we delve deeper into Decoder and Encoder circuits, focusing on critical concepts like creating Higher-Order Decoders from Lower-Order Decoders and understanding the Priority Encoder clearly. The session includes practical examples to clarify how complex decoders (4×16, 6×64) can be constructed using simpler (2×4, 3×8) decoders, complete with logical explanations and step-by-step circuit analysis. Additionally, we extensively cover the priority encoder, including its truth table, priority assignments, and K-map simplifications.
🔹 Topics Covered:
• Higher-Order Decoder using Lower-Order Decoder
• Practical Examples: 4×16, 6×64 Decoders using 2×4 Decoders
