• To create a band-pass filter, select both Highpass and Lowpass.

Enter values into the text boxes, or click in the graph with the

left and right mouse buttons to set the two corner frequencies.

When both filters are active, the individual filters are shown on

the graph in light blue.

• Enter a value in the Gain (dB) box to change the gain of the

filter.

In the example above, the overall gain of the band-pass filter has

been set to 10 dB. This is done by applying a 5 dB gain to each

of the component filters. As a result, the light blue traces

appear 5 dB below the dark blue trace.
