decimal to bcd priority encoder 10 inputs 15 decimal

16 Answer: A Clarification: An encoder is a combinational circuit encoding the information of 2 n input lines to n output. How many outputs will a decimal-to-BCD encoder have A. So, a total of 10 inputs are there in a decimal-to-BCD encoder. In general, if n and m are respectively the numbers of input and outputĭecoders are widely used in the memory system of computers. Thus, a Decimal-to-bcd converter has decimal values as inputs which range from 0-9. If there are some unused or ‘don’t care’ combinations in the n-bit code, then there will be less

BCD to decimal ( 4 – 10 line decoders).

Binary to Hexadecimal (4 X 16 line decoder).

In other words, it performs the reverse operation of an encoder.ĭecoders are used to identify or convert a particular code for example Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above.A decoder is a combinational circuit that converts an n-bit binary input data into 2^n output lines, such that each output line will be activated for only one of the possible combinations of inputs.ĭecoders are usually represented as n-to-2 ^n line decoders, where n is the number of input linesĪnd 2^n is the number of maximum possible output lines.

This article is contributed by Harshita Pandey. It is highly recommended that you practice them. All questions have been asked in GATE in previous years or in GATE Mock Tests. Practicing the following questions will help you test your knowledge. These TTL encoders feature priority decoding of the inputs to ensure that only the.

Other applications especially for Priority Encoders may include detecting interrupts in microprocessor applications.

Encoders are used to translate the decimal values to the binary in order to perform the binary functions such as addition, subtraction, multiplication, etc.

Encoders are very common electronic circuits used in all digital systems.

Then, the output of encoder will be the ( code corresponding to the active High inputs, which has higher priority. So, to overcome these difficulties, we should assign priorities to each input of encoder.

If more than one input is active High, then the encoder produces an output, which may not be the correct code.

There is an ambiguity, when all outputs of encoder are equal to zero.
