Little problem with waves

  1. Jan 10, 2005 #1
    Data file is a text file. there are 2 columns of integers < 2^16.
    these numbers in data files represent input and output signals of some device.
    input signal is cosinus wave with constant component. output signal is also a periodic signal.

    Program should find amplification of described device for fundamental frequency, each harmonic percentage in output signal and non-linear distortion coefficent of output signal.

    This is my C program... and I need to calculate these two underlined things and i don't know how... could you help me, please?? and could you explain what is this non-linear distortion??

    thank you,
