Hi Wayne, If I have a 'scope and a swept audio generator, what else is required to produce a frequency respose graph? Specifically, what's required to plot the response of an active crossover? Would I need some sort of a log amp to measure in dB? Does the audio generator have to sweep at a particular rate? Is there a PC program to do the same thing, maybe easier? The active crossover I made a while ago seems to work really well and I'd like to develop it more (variable freq, HF comp, etc). Thx, Chris
