Hi there all you hardware gurus, 

I need to design a variable bandwidth low pass filter, whose
programmed pass band will span 10kHz to 1MHz. The field is 
open for analog, digital, or any other form of implementation.
The input's dynamic range is about 40dB, and the filter should 
have the properties of a 6 pole Butterworth. Budget should 
be kept at a min. Any ideas out there?

Thanks in advance, David.
