How to record analog data through a microphone jack using MATLAB

Asked by Sunghan Kim
on 25 Jul 2013

Is it possible to record analog data by plugging in a 1/4" phone jack wire into a laptop's microphone jack (1/8") using MATLAB? The analog data has been filtered and amplified by another system.

The situation is that using my laptop (with MATLAB) I would like to display and store a certain type of analog signal that is coming out of an expensive medical device through a 1/4" analog phone jack wire.
