Acerca de URL Encoder / Decoder

This online URL encoder/decoder tool is exceptionally helpful when adding special characters to a URL parameter, which is also often referred to as percent-encoding. The system of URL encoding includes the substitution of unacceptable characters with % (percent sign) and additional hexadecimal values. URL interpreting also works if you want to identify the source of an email marketing campaign or publication.

what is encoder?

An encoder is a digital circuit that performs the inverse operation of a decoder. An encoder has 2" (or less) input lines and n output lines. The output lines generate binary code corresponding to the input value. An example of an encoder is the octal-to-binary encoder, which has eight inputs, each octal. One for the digits, and three outputs that generate Connected binary numbers. It is assumed that only one input has a value of 1 at any given time; otherwise, the circuit makes no sense.

Encoders can be executed with OR gates whose inputs are determined directly from the truth table. Outputs A, 1 if the input octal digit is 1 or 3 or 5 or 7. The same terms apply for the other two outputs. These terms can be defined by Boolean functions: The encoder can be executed with three OR gates.

  • A0 = D1+D3+D5+D7
  • A1 = D2+D3+D6+D7
  • A2 = D4+D5+D6+D7

what is decoder?

Decoder The discrete quantity of information is displayed in a digital computer with binary code. A binary code of ñ bits is capable of representing 2" specific elements of the coded information. A decoder is a combinational circuit that then converts the binary information from the coded input to at most 2" unique outputs. If the n-bit coded information contains unused bit combinations, the decoder may have fewer than 2" outputs.

Definition of decode

decoders are called n-to-m-line. decoders, where ms 2n. Their objective is to generate 2" (or less) binary combinations of n input variables. A decoder has n inputs and m outputs and is called n X Also called m decoder.

The three data inputs, A0, A¹ and A³, are decoded into eight outputs, each representing one of the combinations of the three binary input variables. Three inverters provide the complement of the inputs, and each of the eight more gates produces one of the binary combinations. A special application of this decoder is binary-to-octal conversion. The input variable represents a binary number and the output represents the eight digits of the octal number system. However, a 3-to-8-line decoder can be used to decode any 3-bit code, providing eight outputs for each combination of binary codes.

The commercial decoder includes one or more enable inputs to control the operation of the circuit. The decoder is enabled when E is equal to 1 and disabled when E is equal to 0.

nand gate decoder :-

Some decoders are made from NAND instead of AND gates. Since a NAND gate produces an AND operation with an inverted output, it becomes more economical to generate the decoder outputs in their complement form. Shown in the 2-to-4-line Decoder with an Enable Input built with NAND gates. The circuit operates with a complement output and a complement enabled input E. 

Decoder is able when e equals 0. Only one output equals 0 at any given time; The other three outputs are equal to 1. An output whose value is equal to 0 represents the equivalent binary number in inputs A1, and A0. 

The circuit is disabled when E equals 1, regardless of the values ​​of the other two inputs. When the circuit is disabled, no output is selected and all outputs are equal to 1. In general, a decoder can work with either complement or incomplete outputs. Enable input can be activated with 0 or 1 signal level. Some decoders have two or more enable inputs that must satisfy a given Argument condition to enable the circuit.

What is meant by encoding and decoding?

Encoding is like implementing some algorithm or computation. This can be done to compress data, or to hide information for cryptographic purposes, or to represent it in a specific format.

Decoding is the opposite process of encoding. It outputs the original data.

  1. If the data is encoded to be compressed, decoding will produce the same data (in case of lossless compression) and identical data (in case of harmless compression).
  2. If encoding is done to hide information for cryptographic purpose, decoding will return the original data.
  3. When we have encoded data to represent it in a specific format, decoding will make it reader for software which will represent it in its actual format.

In layman terms, encoding is like wrapping an object and decoding is like removing the cover so that the real object is visible.

What is encoding and decoding in communication?

Encoding means the creation of a message (which you want to communicate with the other person). On the other hand, decoding means listening to Listener or Encoded Message. So decoding means explaining the meaning of the message. ... You will explain the message and understand what has just been said.
