| All filters have phase shift. Tell us what you are trying to accomplish. | |

| so,its not possible to find a filter with zero phase shift?cos i need to find a low pass filter that filter filter off 180hz onwards,while maintaining as much gain of 1 as possible.or else,need to compensate back.also,need to shift back whatever phase change. can a simple RC cct do that?i need to maintain 1mA into the LPF,so the R may have to be very big.... | |

| What is the signal you're trying to filter? Why do you need zero phase shift? | |
