Filter-Design

Features

  • Implementation a website to design a custom digital filter via zeros-poles placement on the z-plane.
  • Modify the placed zeros/poles by dragging them.
  • Clicking on a zero or pole and delete it.
  • Clearing all zeros or clear all poles or clear all.
  • Has the option to add conjugates automatic.
  • A plot that shows the corresponding frequency response for the placed elements: One graph for the magnitude response and another graph for the phase response.
  • Apply the filter on a signal as if it is a real-time filtering process.
  • A graph shows the time progress of the signal.
  • Another graph to show the time progress of the filtered signal .
  • Control the speed of the filtering process (i.e the filter can process 1 point per second or 100 points per second or any number in between via a slider.
  • Correct for the phase by adding some All-Pass filters.
  • Picking the suitable all-pass through a library available in website to add to original filter
