## What is decoder explain 3 to 8 line decoder with diagram?

A 3 to 8 decoder has three inputs (A, B, C) and eight outputs (D0 to D7). Based on the 3 inputs one of the eight outputs is selected. The truth table for 3 to 8 decoder is shown in the below table. From the truth table, it is seen that only one of eight outputs (D0 to D7) is selected based on three select inputs.

## What is a 3 to 8 line decoder?

3 to 8 line decoder: The 3 to 8 line decoder is also known as Binary to Octal Decoder. In a 3 to 8 line decoder, there is a total of eight outputs, i.e., Y0, Y1, Y2, Y3, Y4, Y5, Y6, and Y7 and three outputs, i.e., A0, A1, and A2. This circuit has an enable input ‘E’.

How many select line enable line will be there in 3 * 8 decoder?

Answer: Total 8 select lines out of which one is selected. Explanation: The 3:8 decoder is also known as binary to octal converter.

How do you implement a 3/8 decoder Adder?

Procedure

1. Place the IC on IC Trainer Kit.
2. Connect VCC and ground to respective pins of IC Trainer Kit.
3. Implement the circuit as shown in the circuit diagram.
4. Connect the inputs to the input switches provided in the IC Trainer Kit.

### What is decoder explain with diagram?

Advertisements. Decoder is a combinational circuit that has ‘n’ input lines and maximum of 2n output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled. That means decoder detects a particular code.

### What is decoder explain?

A decoder is a multiple-input, multiple-output combinational logic circuit. It converts the n bit data inputs into the coded 2n outputs. It decodes the information hidden by the encoder. While decoding, the decoder generally places logic 1 at one of its outputs to create the exact code.

How many 3 to 8 line decoders with an enable input are needed to construct a 6?

GATE | GATE-CS-2007 | Question 85 How many 3-to-8 line decoders with an enable input are needed to construct a 6-to-64 line decoder without using any other logic gates? hence required decoders (from fig.) = 9 so ans is ( C) part.

What is the need of decoder make a 3/8 decoder using 2 to 4 decoder?

The block diagram of 3 to 8 decoder using 2 to 4 decoders is shown in the following figure. The parallel inputs A1 & A0 are applied to each 2 to 4 decoder. The complement of input A2 is connected to Enable, E of lower 2 to 4 decoder in order to get the outputs, Y3 to Y0.

#### What is a decoder circuit?

A decoder is a circuit that changes a code into a set of signals. It is called a decoder because it does the reverse of encoding, but we will begin our study of encoders and decoders with decoders because they are simpler to design.

#### What is decoder explain how full adder can be implemented with decoder?

A decoder accepts a binary encoded number as input and puts a logic 1 on the corresponding output line. For 2 inputs -> 4 output lines. 3 inputs -> 8 output lines. eg for 3 inputs with the signal 101 on them: the 5’th output line will be 1, the rest 0.

What is line decoder?

Decoder is a combinational circuit that has ‘n’ input lines and maximum of 2n output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled.
