2 channel data acqusition understand how to acquire signal

[integralx2]

I need to record a 2 channel EMG signal. I plan to use an instrumentation amplifiers. After I get the results I need to feed the two channels into ADC. The thing I dont get , is how do we analyze two separate signals ? I know I will use a MUX before it goes into ADC. I kind of dont understant whats the benefit of using two channels ? What can i do with the two results after I feed them into the MUX? When analyzing the signal would i have to analyze them seperetaly, and then I can display them ? Or do i add the signals together ? I dont get this part, of having two channels, and what to do with the results of the two channels.

Hello,

The analysis on the signals is dependant on your application.  You can choose not to analyze the signals and just save them to file, or LabVIEW has a diverse amount of pre-built analysis VI's in the functions library.  I'm a little confused at what you are asking here, what benefit are you talking about?  If you have two channels coming out of your EMG, you need to acquire both channels on their own separate channels with your data acquisition board.  The MUX is used simply so that a single ADC is used, but the two channels are still separated in your code based on the channel they were acquired from.  You can choose to display the signals separately or together, it makes no difference.
