LOGIC DIAGRAM FOR 3 TO 8 DECODER
3 to 8 Line Decoder : Designing Steps & Its Applications
The decoder circuit works only when the Enable pin (E) is high. S0, S1 and S2 are three different inputs and D0, D1, D2, D3. D4. D5. D6. D7 are the eight outputs. The logic diagram of the 3 to 8 line decoder is shown below. 3 to 8 Decoder Circuit 3 to 8 Line Decoder and Truth Table. The below table gives the truth table of 3 to 8 line decoder.

Combinational circuits using Decoder - GeeksforGeeks
May 26, 2022The input to the full adder, first and second bits and carry bit, are used as input to the decoder. Let x, y and z represent these three bits. Sum and Carry outputs of a full adder have the following truth tables- Therefore we have- The following circuit diagram shows the implementation of Full adder using a 3:8 Decoder and OR gates. References-
What is a Full Subtractor : Construction using Logic Gates
Full Subtractor using Decoder. The designing of a full subtractor using 3-8 decoders can be done using active low outputs. Let’s assume decoder functioning by using the following logic diagram. The decoder includes three inputs in 3-8 decoders. Based on the truth table, we can write the minterms for the outputs of difference & borrow.
Design of BCD to 7 Segment Display Decoder using Logic Gates
As the 7-segments displays on the FPGA development board are common anode, we consider an ON state of a segment as logic 0 and OFF state of a segment as logic 1. Now we can consider each segment of our 7 segment display and construct a combinational circuit for each of them. To ease the simplification, we can draw a 4 input Karnaugh Map. Segment A[PDF]

3. The input and output variables are assigned letter symbols. 4. Construct the truth table to define relationship between inputs and outputs. 5. The simplified Boolean function for each output is obtained (using K-Map, Tabulation method and Boolean Algebra rules). 6. [PDF]
UNIT 4 Memory and Programmable Logic
Figure 2 shows the internal logic construction of the ROM. The five inputs are decoded into 32 distinct outputs by means of a 5 x 32 decoder. Each output of the decoder represents a memory address. The 32 outputs of the decoder are connected to each of the eight OR gates. The diagram shows the array logic convention used in complex circuits .
Branch predictor - Wikipedia
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g., an if–then–else structure) will go before this is known definitively purpose of the branch predictor is to improve the flow in the instruction pipelinech predictors play a critical role in achieving high performance in many modern pipelined microprocessor architectures

Here, 3 to 8 decoder generates eight min terms. The two programmable OR gates have the access of all these min terms. But, only the required min terms are programmed in order to produce the respective Boolean functions by each OR gate. The symbol ‘X’ is used for programmable connections.
