I have an all-pass filter in Proteus, which in theory doesn't change phase. but changes amplitude. How can I see both of the graphs? Here are the needed scheme and its analogue in Proteus. Although I'm not sure if in Proteus I created the same circuit. https://imgur.com/a/AQohBtU

  • \$\begingroup\$ I mean I used the Frequency Response option, and I assume it shows only magntiude response. \$\endgroup\$ – Kedr Mar 20 at 13:25
  • \$\begingroup\$ Right.... What are the 2 graphs you are wanting to see? You say it doesn't change phase, but changes amplitude (in theory) so what is it you are wanting to see on the graphs? Instead of just showing the circuit, can you show us the graph(s) you currently have and say what else you are wanting to add? \$\endgroup\$ – MCG Mar 20 at 13:33
  • \$\begingroup\$ Here're graphs I see and the graph I'd like to see. Is the first one amplitude and the second one phase? imgur.com/a/FRQoPfE \$\endgroup\$ – Kedr Mar 20 at 13:57
