How linear-phase filters can still cause phase distortion

filterwizard • 0 implied HN points • 14 Sep 24
🕹 Technology Signal Processing Audio engineering Data Analysis Filters
  1. Even though linear-phase filters are supposed to keep the phase of signals the same, they can still cause unexpected phase changes. This can happen especially at stopband frequencies where the phase might jump abruptly.
  2. Using simple filters, like box-car filters, can lead to problems because they may not completely block unwanted frequencies. This can result in the output signal being inverted or misinterpreted, especially when analyzing important data trends.
  3. It's important to choose the right filter. Either use filters that effectively block unwanted frequencies or ones that don’t cause abrupt phase changes, to avoid messing up the signals you are trying to interpret.

How to turn linear phase into truly linear phase

filterwizard • 0 implied HN points • 17 Sep 24
🕹 Technology Signal Processing Filters Digital Design Electronics
  1. FIR filters can have phase jumps that can affect signal quality. To fix this, one method is to use two filters in series, which cancels out unwanted phase jumps.
  2. Another approach involves tweaking the filter's impulse response to eliminate negative values in the Fourier transform. This ensures a smoother phase response without major changes to the filter's function.
  3. It's important to over-design the filter's stopband due to the adjustments made. This way, the overall performance remains reliable and avoids distortion in the filtered signals.
