Designing Additional Filters

You have designed one of the bands of an octave filter bank. This section shows you how to design and save the other nine bands. The following table defines the parameters for the remaining bands. Note that all of the bands use these parameters: Bandpass, IIR – Butterworth , order = 6, Fs = 48000 Hz .

Fc1	Fc2	Filter Name
45	89	Bandpass Butterworth-2
89	178	Bandpass Butterworth-3
178	355	Bandpass Butterworth-4
355	708	Bandpass Butterworth-5
708	1413	Bandpass Butterworth-6
1413	2818	Bandpass Butterworth-7
2818	5623	Bandpass Butterworth-8
5623	11220	Bandpass Butterworth-9
11220	22387	Bandpass Butterworth-10

1. Using the parameters listed in the table above, for each table row, set the appropriate the Fc1 and Fc2 values.

2. Design the filter by clicking the Design Filter button.

3. Click Store Filter to save the filter.

4. Change the name to the appropriate filter name shown in the table above.

5. Repeat these steps until all 10 filters are designed and stored.
