Question
Which of the following is used to convert a binary-coded decimal (BCD) input into signals that can display decimal digits on a seven-segment display?a.Shift registerb.Parity generatorc.Decoderd.Encoder
Solution
The correct answer is c. Decoder.
Here's why:
A binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each decimal digit is represented by a fixed number of bits, usually four or eight.
A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.
A decoder is a combinational circuit that converts binary information from n input lines to a maximum of 2^n unique output lines. In the case of BCD to seven-segment display decoder, it takes the BCD as input and outputs the relevant signals to display the decimal digit on the seven-segment display.
So, a decoder is used to convert a binary-coded decimal (BCD) input into signals that can display decimal digits on a seven-segment display.
