The request
“Draw a 5 V 2-to-1 analog audio multiplexer that selects between a microphone input and a line input with a source-select control and a 10 kΩ output load.”
Then tryAdd a mute control.Change the line input to 2 V peak-to-peak.
What is in this drawing
Read the decisions behind it.
01Two source inputs
Microphone and line level feed the selector.
02Select control
One signal chooses the active source.
03Loaded output
The output feeds the next audio stage.
