1. I have a filter specs which i need to implement. Specs are: (in inverted commas)

"When switch is pressed, the filter is included with range 10Hz-1000Hz and bandwidth of filter is 23% for broad band analysis"


2. I am using labview. I have placed a filter with below specs:
Mode: IIR filter
Order: 6
Type: bandpass
fl = 10Hz
fh=1000Hz
Topology: butterworth

3. In specs i didn't understand the bandwith thing:23%.
When already filter fl & fh are given, what is this 23%.
I think specs are misprinted.
