If "cutting value" means corner frequencies. then you combine a low pass filter and a high pass filter set at those value. The passband is the range of frequencies between the lower and upper corners.

Do you know what those cutting values represent? As beenthere said, they might mean the corner frequencies of the bandpass filter which essentially are used to "cut" out all other frequencies that are to be passed. Those values are represented by this equation:

cut freq = 1 / (2*pi*R*C)

So you can go from there and figure out what your R and C values will be. You can check the ebook I think for circuit configuration.

you can also achieve your passband circuit with the use of one opamp configured as a multifeedback or use two cascaded opamps as a sallen key.
