Need a bump filter design.

[elshout]

Could someone provide a schematic for a filter with a + 6 db boost at 20 Hz with a Q=2?

Any help would be greatly appreciated.

frequency response fig.14.

Helpful? (Don't know the term "bump filter")

Thanks for the reply Hoerninger. What type of power would this take? Also, what software did you use to create the graph you included in your response?

Depending on the opamp about +/-15 V dc. If you will use the one transistor solution Keele mentioned you will come along with a single rail dc of about +20 V.

Also, what software did you use to create the graph you included in your response?

I used Electronics Workbench. Other programs will be useful too as the circuit is not complicated. (Spice).

Bessel and Chebychev filters are bump filters.
