CREATE A BANDPASS FILTER WITH SLOPE, AND TWO CUTOFF FREQUENCIES

Hi. I have a problem with Bandpass Filters. I need to create a bandpass filter with a slope of 60 dB per octave, and I need to have my passband between 90 HZ and 381 HZ.

My question is: how can I control this parameters in a Banpass filter? I suppose I shall use a reson~, a biquad~ or a fffb~... But I was not able to find in the Help or in the Reference what I was looking for.

Am I missing something?

biquad.

first 5 biquads as highpass at 90hz and then 5 biquads as lowpass at 381hz, all in series.

we have filterdesign and cascade to manage this for us.

Thanks, stkr. Your solution is exactly what I was looking for... since 1492!
