Bi Quad Filters Question

[arunramnath]

A general Question on BiQuad filters.

I come across the term 3 band Bi quad filters. THis has three Biquads cascaded. So, does the term mean that we can have three band of frequencies suppressed/filtered when we use this?

I THINK what is meant is that you can have lowpass, highpass and bandpass outputs, not different frequencies.

Thanks Barry. This means out of the whole frequency band, we can choose the bands required by us and filter the rest. Two band passes towards lower frequency and One high pass?
