Realtime Digital Filter Design Application

Overview

This desktop application allows users to design custom digital filters by placing zeros and poles on the z-plane. The interactive interface provides real-time visualization of the filter's frequency response and enables users to apply the designed filter to lengthy signals with customizable temporal resolution.

Features

Z-Plane Plot

  • Interactive Plotting: Users can place zeros and poles on the z-plane.
  • Dynamic Modifications: Zeros/poles can be modified by dragging them.
  • Deletion: Clicking on a zero or pole allows users to delete it if delete by click mode is activated.
  • Clear Options: Users can clear all zeros, all poles, or clear everything on the Z-plane.
  • Conjugates: Option to add or remove conjugates for complex elements.

Frequency Response Plot

  • Magnitude and Phase Response: Visual representation of the filter's frequency response.
  • Real-time Updates: The plots update as users modify the filter design.

Real-time Filtering

  • Lengthy Signal Processing: Apply the filter to a signal with a minimum of 10,000 points in real-time.
  • Mouse Input: Users can input real-time signals by moving the mouse, with the speed affecting signal frequencies.

Phase Correction with All-Pass Filters

  • All-Pass Filter Library: Visualize and select from a library of all-pass filters.
  • Custom All-Pass: Users can create their own all-pass filters by specifying "a," and the application calculates its phase response.
  • Enable/Disable Controls: Users can toggle the added all-pass elements.
