## What is the normal operating conditions of a decoder that corresponds to input and output states.

ANSWER : E=0 and Outputs at “0” logic state. This question does not have an explanation.

**What does a 3 to 8 decoder do? **

This decoder circuit has 8 logic outputs for three inputs and an enable pin. This circuit uses both AND and NAND logic gates. It accepts three binary inputs and activates one out of eight outputs. A binary to an octal circuit, which is a 3-8 line decoder circuit, is also known as a binary-to-an-octal decoder.

### How many and gates are required to implement a 3/8 decoder?

The circuit of a 3-8 decoder can use three NOT gates or eight 3-input AND gates, as shown in figure (1). Each output represents one of the three input variables A, B, and C.

**What does a decoder do? **

Chapter9 – Combinational logic functions A decoder converts a code into signals. Because it reverses encoding, it is called a “decoder”. However, we will start our study on encoders and decoders using decoders as they are easier to design.

#### What encoder means?

An encoder, or “simple coder” in digital electronics, is a one-hot binary converter. If there are 2n input lines and only one will ever be high, an encoder (or “simple encoder”) in digital electronics is a one-hot to binary converter. The binary code of the hot line is generated on the n bit output lines. Binary encoders are the equivalent of binary decoders.

**Why do we use encoder? **

An encoder is a sensor which detects linear displacement or rotation angle. Devices that require high speed and high accuracy will use encoders.

## What is priority encoder explain with example?

From Wikipedia, the free Encyclopedia. A priority encoder is an algorithm or circuit that reduces the number of binary inputs to produce fewer outputs. A priority encoder’s output is the binary representation the original number, starting at zero of the most important input bit.

**How do encoders work? **

Encoders convert movement to an electrical signal that is read by any type of control device within a motion control system such as a counter, PLC or PLC. The encoder transmits a feedback signal which can be used for position, count and speed as well as direction.

### Why encoder is used in the digital electronics?

Encoders can be found in almost all digital systems. To convert decimal values into binary, encoders are needed to perform binary functions like addition, subtraction and multiplication.

**How many possible outputs would a decoder have with a 6 bit binary input? **
