Which of the following is commonly used to drive a seven-segment display to show numeric digits?a.Counterb.Multiplexerc.Shift registerd.Decoder

The most commonly used device to drive a seven-segment display to show numeric digits is a Decoder.

Here's why:

a. Counter: A counter is a device that counts the number of times an event occurs. While it can be used in conjunction with a seven-segment display, it doesn't drive the display itself.

b. Multiplexer: A multiplexer is a device that selects one of many inputs and forwards the selected input into a single line. It's not typically used to drive a seven-segment display.

c. Shift register: A shift register is a type of register that allows its contents to be moved from one bit to another. While it can be used to control a seven-segment display, it's not the most common method.

d. Decoder: A decoder is a circuit that changes a code into a set of signals. It is commonly used to drive a seven-segment display because it can take a binary input and output a number on the display. For example, a BCD (Binary-Coded Decimal) to 7-segment decoder takes a four-bit binary input and outputs a number on the seven-segment display.

So, the answer is d. Decoder.
