Z-plot

iPad / Utilitaires

Tired of learning z-transform / DSP?
This app helps you build up intuitions of filter design. Place zeros and poles on the z-plane at will, and see the filter response immediately. You can even unlock the hidden mode to listen to the filtering effect on a sound track, and you can dance with every plot.

Quoi de neuf dans la dernière version ?

1. Now support click and drag feature. It's much easier to compare the effect of deviating poles and zeros.
2. Since it's quite difficult to click at the same place twice, we cancelled the old object selecting method. Now you have to explicitly
choose the object (zero, pole, double zero, double pole and the eraser) before placing them.
3. Now the rainbow is unlocked by default. 
4. New icon. Have a nice day EEers!
