VARIABLE HIGH PASS / LOW PASS FILTER DESIGN HELP NEEDED!!!?
Im trying to design a simple home made unit for recording line level instruments through.
Simply put, I want a brick wall high pass filter with a variable cut off frequency and a brick wall low pass filter with a variable cut off frequency in one unit. I plan on using it to enhance my home recordings. It seems like this should be simple to design and build (with a small number of components!) but I can find precious little information on schematics or design instructions on the internet for these filters.
Can anyone point me towards some instructions or anything? Or maybe even post some instructions? I would appreciate it. Thanks.
