I learned about multiplexers MUX which select one of many input signals and forward the chosen input to a single output line using select lines to determine which input is chosen This is crucial in digital circuits for routing data efficiently I also studied the full adder which adds two binary digits along with a carry in from a previous addition producing both a sum and a carry out This allows for the cascading of adders to perform multi bit binary addition Encoders and decoders were another focus a decoder takes binary inputs and activates one of several outputs useful in memory addressing while an encoder does the opposite reducing multiple inputs to a smaller binary output These components are foundational in designing efficient and scalable logic circuits often combined with techniques like Karnaugh maps K Maps to optimize the logic The use of these devices particularly in larger digital systems streamlines how we process and manipulate binary data Summary Confusion I m still unclear on how the carry look ahead adder differs in performance compared to a regular ripple carry adder Additionally I m not fully understanding how the use of priority encoders simplifies certain decision making processes in circuits
