Question
what is the output of a demux when one control line is high and others are low? a. all outputs are lowb. all outputs are high c. corresponding output is high, others are low d. corresponding output is low, others are high
Solution
The output of a demultiplexer (Demux) when one control line is high and others are low is: c. corresponding output is high, others are low.
Here's why:
A demultiplexer (Demux) is a device that takes a single input line and routes it to one of several digital output lines. A Demux of 2^n outputs has n select lines, which are used to select which output line to send the input.
The control lines determine which output line the input should be sent to. If a control line is high (1), the input will be sent to the corresponding output line. If the control line is low (0), the input will not be sent to the corresponding output line.
So, if one control line is high and the others are low, the input will be sent to the output line corresponding to the high control line, and all other output lines will remain low. Hence, the answer is c. corresponding output is high, others are low.
