    Hi.
    Here is my task:
    Find ratio R1/R2 so that zero and pole of transfer function are spaced for one octave.

    But what "spaced for one octave" means?

    From MathWorks: An octave is the interval between two frequencies having a ratio of 2:1
    Here is a bit more explanation: http://www.diku.dk/~jda/biosignal/lab10.pdf

    Lets say you pick a frequency of 1 kHz. Now multiply it by 2, 2*1 kHz= 2 kHz. The range of frequencies from 1 kHz to 2 kHz is an octave.
