Control System Toolbox For TI-89 (CST)
Web app for experimenting with control systems
Control Systems: HP prime app with frequency, time domain and root locus plots
A Python/MATLAB project which implements pulse-code modulation (PCM) and delta modulation (DM).
Livro-texto de controle clássico em português, gratuito e com MATLAB integrado ao método. Lugar das raízes, Routh-Hurwitz, Bode, Nyquist e projeto de compensadores nos domínios do tempo e da frequência.
A library for studying LTI dynamical systems
Analysis plugins for the Audacity audio editor (and its forks Audicium, Tenacity, etc)
DC-Motor analysis, transfer function is given.
Simulation showing how a signal can be reconstructed based on the sampling frequency
An illustrator for the signal recovery that shows the importance and validation of the Nyquist rate.
Real-time ultrasonic spectrum display using your microphone. Captures audio via PortAudio (sounddevice), computes an FFT, and plots only the ultrasonic band (>20 kHz). Includes a control panel to adjust device, sample rate, block size, min frequency, and FFT size while running.
A python script that implements an automatic speech recognision system.
Interactive control-systems plotter — type a transfer function, get Bode, Nyquist, Nichols, pole-zero, and step-response plots live.
Code snippets and notebooks used in PDS classes.
