    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
    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.
