## What is priority encoder design a 4 2 priority encoder?

Priority Encoder – A 4 to 2 priority encoder has 4 inputs : Y3, Y2, Y1 & Y0 and 2 outputs : A1 & A0. Here, the input, Y3 has the highest priority, whereas the input, Y0 has the lowest priority.

### Can encoder be a multiplexer?

10. Can an encoder be called a multiplexer? Explanation: A multiplexer or MUX is a combination circuit that contains more than one input line, one output line and more than one selection line. Whereas, an encoder is also considered a type of multiplexer but without a single output line and without any selection lines.

#### What is priority encoder explain with example?

A priority encoder is a circuit or algorithm that compresses multiple binary inputs into a smaller number of outputs. The output of a priority encoder is the binary representation of the index of the most significant activated line, starting from zero.

What is 8×3 encoder?

The 8 to 3 line Encoder is also known as Octal to Binary Encoder. In 8 to 3 line encoder, there is a total of eight inputs, i.e., Y0, Y1, Y2, Y3, Y4, Y5, Y6, and Y7 and three outputs, i.e., A0, A1, and A2. In 8-input lines, one input-line is set to true at a time to get the respective binary code in the output side.

What is the difference between encoder with priority and without priority?

The main difference between encoder and priority encoder is- the encoder generates an error output when more than one input is high. But they are used in applications compressing data. Hence, priority encoders are introduced to overcome the issues of binary encoders.

## What is dual priority encoder?

In priority encoder, if two or more inputs are equal to 1 at the same time, the input having the highest priority will take precedence. In case of dual-priority encoder, the circuit identifies both the highest-priority and the second-highest-priority asserted signal among a set of input signals.

### Which type of basic Gates is most necessary for encoders?

Encoders are made by three OR gates. Octal to Binary Encoder has eight inputs, A7 to A0, and three outputs B2, B1 & B0. The Truth table of octal to the binary encoder is shown below.

#### How does an encoder different from a decoder?

Encoder circuit basically converts the applied information signal into a coded digital bit stream. Decoder performs reverse operation and recovers the original information signal from the coded bits. In case of encoder, the applied signal is the active signal input. Decoder accepts coded binary data as its input.

What are priority encoders explain 4 bit priority encoders?

The priority encoder is a circuit that executes the priority function. The logic of the priority encoder is such that two or more inputs appear at an equal time, the input having the largest priority will take precedence. The truth table of a four-input priority encoder is given in the table.

What is a 4 to 16 decoder?

A 4-to-16 decoder consists of 4 inputs and 16 outputs. Similar to all the decoders discussed above, in this also only one output will be low at a given time and all other outputs are high (using maxterms). The truth table of this type of decoder is shown below.

## What is a 4 to 2 line encoder?

A 4 to 2 line encoder consists of 4 input lines and 2 output lines. When any of the input lines becomes 1, we get corresponding binary at the output lines. Truth table of 4 to 2 line encoder is, Advertisements.

### How many inputs will a decimal to BCD encoder have?

ten input lines
Decimal-to-BCD encoder is the type of encoder that usually consists of ten input lines and 4 output lines.

#### What is 8 to 3 encoder?

The 8 to 3 Encoder or octal to Binary encoder consists of 8 inputs : Y7 to Y0 and 3 outputs : A2, A1 & A0. Each input line corresponds to each octal digit and three outputs generate corresponding binary code. The figure below shows the logic symbol of octal to binary encoder: The truth table for 8 to 3 encoder is as follows :

A 4 to 2 line encoder consists of 4 input lines and 2 output lines. When any of the input lines becomes 1, we get corresponding binary at the output lines.

What is 8-3 encoder?

The working and usage of 8:3 Encoder is also similar to the 4:2 Encoder except for the number of input and output pins. The 8:3 Encoder is also called as Octal to Binary Encoder the block diagram of an 8:3 Encoder is shown below Here the Encoder has 8 inputs and 3 outputs, again only one input should be high (1) at any given time.

How many inputs and outputs does a 4-2 encoder have?

It has four inputs and two outputs so the name of this Encoder will be 4:2 Encoder. If an Encoder has “ n ” number of output lines then the number of input lines will be 2­ ­
