On step 4 of the Design Instructions in Section 3 (p.3), what are the parameters we should enter into Webench?
The only parameter that matters for the filter design itself in Webench is “Overall System Gain.” All the other parameters are for National’s script to help you find a National part to use in your design, but since we’ve already decided on the LT1677 for the Audio and the LT1363 for the IF (sorry National), those don’t really matter for us.
