Output of the filter design pgm is in terms of varoius LTC op amps etc but useful if you want to get an appreciation of what may be needed to achieve a given spec. Can't recall the options available but I dare say yu will have a peek anyway! The handbook(downloadable too) for use with the software is quite interesting as well. 73 Dave, ZL3FJ
