Science and technology has introduced several concepts, which paves down the way for humanity to solve and calculate complex logical problems in most efficient and effective way. One such milestone in the field of binary system is the introduction of a binary decoder.
What is a Decoder?
Decoder is an instrument developed to understand or comprehend a code, which makes the entity complex and secret. A decoder detects the code that is encrypted and activates the output in the form of a signal that clearly describes the code. A decoder has various applications ranging from developing alert systems in alarms and performs the function of integrating and driving various devices embedded in a microprocessor.
What is a Basic Binary Decoder?
The function of a basic binary decoder is to ascertain that whether a given input value has any combination function. Let us consider a digital circuit of a voltammeter. If we desire to detect 1011 occurs on the various inputs of the circuit in consideration then we have to develop a decoder that would decode only the output in the form of 1. In accordance, we would develop a 4-input AND gate to ascertain the input value.
What is a Three-Bit Binary decoder?
In case of three bits circuit or a three-bit code, eight logic gates will be required to decode all the possible combinations. The reason is obvious in a three-bit code the maximum possible binary code would be 23=8. The other name for this decoder is the 3 –line to 8-line decoder as it involves 3 inputs and 8 outputs. For a three-BIT decoder high active output are required. 3-line-to-8-line decoder is also known as 3 * 8 decoder.
The BCD-to-Decimal Decoder
The BCD- to- Decimal decoder is one other binary decoder which converts the BCD code to decimal system. The BCD decimal decoder functions on the similar technique of a 3-line-to-8-line decoder.
What is a Binary Encoder?
A Binary encoder performs actually the opposite function that of a binary decoder. It is a combination logic circuit, which essentially encrypts the binary code. An encoder first accepts an active in the form of binary digit 1, on its input receiving unit that represents a decimal digit and then converts it to an output that is coded in the form of binary BCD. This process of converting symbols and numbers to an incomprehensive complex format is termed as encoding.
What is Decimal-to-BCD Encoder?
With the BCD format, ten decimal digits are described as 4 binary digits. Thus, a decimal to BCD encoder has 10 inputs and 4 outputs. This encoder is also termed as 10-line-to-4 line decoder.
Thus, binary decoder is an important tool, which supports the encoding and decoding of binary digits or code to decimal and vice-versa. The decoder ensures the correct coding process as well as supports in the logical interpretation and deduction of code.
