MATLAB: 16 bit signed data to integer for analysis

Question

Hi, I am trying to convert 16 bit signed data from my machine to convert to radians. I am a bit confused as to how I can convert per say +1024 into 2pi and -1024 into -2pi. Is there a function that can first convert the 16bit signed data into real number for me?

Thanks, Atique

Answer 1

double(X)/1024 * 2*pi

However, normally angles are in the range -Pi to +Pi or 0 to 2*Pi. If you wanted -1024 to correspond to -Pi and +1024 to correspond to +Pi then change the 2*pi above to just pi
