Dear signal processing enthusiasts:
I am forced to cut off a part of a multi-frequency signal, creating a "gap" as shown in the figure. (only one frequency to simplify illustration).
If I inject part A of the signal into a FIR which has linear phase vs frequency, and set the FIR to have a group_delay proportional to the gap length, the output's phase doesn't change, and hence the stitched signal has a phase jump.
I am looking for a filter that would let part A propagate through, to the point where its phase matches part B's phase. Does such a filter exist?
