Nyquist is a language for sound synthesis and music composition.
Nyquist is a language for sound synthesis and music composition. It is implemented in C and C++ and runs on Win32, OSX, and Linux. Nyquist combines a powerful functional programming style with efficient signal-processing primitives. Nyquist is also embedded as a scripting language in Audacity.

Turn your PC into the ultimate shortwave radio. Skywave Linux is an X86, 64 bit live environment configured for accessing internet accessible software defined radio receivers.
With this operating system, you may tune in popular stations or amateur radio, aeronautical, maritime, or other signals received at remote internet servers around the world. For a live map of the best KiwiSDR and WebSDR servers and a nice "click to tune" interface, Use the installed SDR-Map...

Stop waiting on engineering. Build production-ready internal tools with AI—on your company data, in your cloud.
Retool lets you generate dashboards, admin panels, and workflows directly on your data. Type something like “Build me a revenue dashboard on my Stripe data” and get a working app with security, permissions, and compliance built in from day one. Whether on our cloud or self-hosted, create the internal software your team needs without compromising enterprise standards or control.
...Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms.
Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.
Electric Behaviour of Crystals and Pierce Crystal Oscillators
The Java applet QuartzCrystal shows the frequency response of quartz crystals and Pierce crystal oscillators. Crystal parameters can be freely choosen. Display is spectrum analyzer-like and shows the amplitude/phase and/or a Nyquist diagram. Crystals can be series resonant or with load capacitance. Adding of spurious resonances is possible.
ENIAC: Electrical Network Interactive Analysis Console. Educational software originally made for the study and simulation of electrical LTI circuits, but which supply also a lot of mathematics computations, like complex, polynomial and matrix operations.
Représentation Bode (asymptotique et réelle), Nyquist, Black, d'éléments du premier et du second ordre. Le programme est en Java developpé avec NetBeans.
