What is a decoder Verilog?

What is a decoder Verilog?

A decoder is a combinational logic circuit that has ‘n’ input signal lines and 2n output lines. In the 2:4 decoder, we have 2 input lines and 4 output lines.

How many gates are required to design the 3/8 decoder?

From the above Boolean expressions, the implementation of 3 to 8 decoder circuit can be done with the help of three NOT gates & 8-three input AND gates.

How do you implement a 3/8 decoder?

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.

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 can we design a decoder?

Once understood the previous issue, you could design your own decoders.

1. Step 1: Decoder’s Inputs. In this step, you need to define what you want to do at the beginning of the process and having a clear idea of your project.
2. Step 2: Decoder’s Equations.
3. Step 3: Decoder’s Diagram.

How many 3/8 decoders are needed if you are going to a 6 to 64 decoder?

9
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.

How many inputs are required for a 6 to 64 decoder?

The answer is 4. Say the 8 input variables are A,B,C,D,E,F,G,H. Pass C,D,E,F,G,H as inputs to each of the four 6->64 decoders.

What is full subtractor?

The full subtractor is a combinational circuit which is used to perform subtraction of three input bits: the minuend , subtrahend , and borrow in . The full subtractor generates two output bits: the difference and borrow out . is set when the previous digit is borrowed from .

How many 3/8 line decoders with an enable input are needed to construct a 6 64 line decoder without using any other logic gates?

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.
