TCP/IP EEG data transform

Post by liming » Tue Aug 21, 2018 4:16 pm

Dear all,

I'm writing a program to receive EEG data from ActiView through TCP/IP communication. Then I convert the 24 bit data into decimal number. But I'm confused about the correspondence between the decimal number and the real-time data shown in ActiView. The maximum amplitude of data shown in ActiView is about 200uV. My converted data (e.g. -2.12562e+009) seems too large.
So do you know the correspondence between the converted decimal number and the real-time data in ActiView?

Much thanks in advance

Ming

24-bit integer, EEG channels: LSB = 31.25 nV (1/32th microVolt), so signal range is -262 mV to 262 mV.
