    Hi all ,
    how to calculate the average power of digital samples(I and Q) ??
    in my project ..i am feeding IF signal ( GMSK modulated with power of -20db to -60db) to ADC (analog to digital converter ) and from ADC to digital down converter chip , i need to calculate the power of digital output samples (I and Q) of Down converter chip

    for 156 samples , the average power would be : ((I^2+Q^2))/156.
    if-20 db power is fed as an input .. the calculated value with the formula is not matching to -20db .. ??
    kindly help
