Looking for something very simple, just to visually compare different crossover points and slopes. Is there anything like that out there?
This is an active crossover, so don't need circuit design features.
Thanks for the references. I ran into the same situation as the other poster, a lot of overhead to get a graph. I finally ended up just doing it manually. My intention was to get a visual comparison of attenuation between a 2nd order butterworth HP at 1400 vs a LR4 at 1000.
If only the slope is important, just use excel and a semilog plot.
Each 6dB/oct is 20dB/decade.
Say you cross at 1kHz
to plot a lowpass at 6Db/octave you would plat a line 0dB at 1kHz and -20dB at 10kHz
to plot a highpass, 0 at 1kHz, and -20dB at 100Hz
for 24dB/octave it would be -80 at 10x or 0.1x the crossover frequency...
