List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
It may include a rotation of space; a rotation-free Lorentz transformation is called a Lorentz boost. In Minkowski space—the mathematical model of spacetime in special relativity—the Lorentz transformations preserve the spacetime interval between any two events. They describe only the transformations in which the spacetime event at the ...
Quite Universal Circuit Simulator (Qucs) is a free-software electronics circuit simulator software application released under GPL. It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit.
LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). [2] It is the most widely distributed and used SPICE software in the industry. [6]
therefore the explicit form of the boost matrix depends only the generator and its square. Splitting the power series into an odd power series and an even power series, using the odd and even powers of the generator, and the Taylor series of sinh ϕ and cosh ϕ about ϕ = 0 obtains a more compact but detailed form of the boost matrix
(The other similar generator, K y + J x as well as it and J z comprise altogether the little group of the light-like vector, isomorphic to E(2).) The action of a Lorentz boost in the x-direction on the light-cone and 'celestial circle' in 1+2 spacetime.
Lorentz boost of an electric charge. Top: The charge is at rest in frame F , so this observer sees a static electric field. An observer in another frame F ′ moves with velocity v relative to F , and sees the charge move with velocity − v with an altered electric field E due to length contraction and a magnetic field B due to the motion of ...
Micro-Cap [1] is a SPICE compatible analog/digital circuit simulator with an integrated schematic editor that provides an interactive sketch and simulate environment for electronics engineers. It was developed by Spectrum Software , and was only available with a paid commercial license. [ 2 ]
