QUCS VS CircuitLab

Compare QUCS VS CircuitLab and see what are their differences

QUCS logo QUCS

Qucs, briefly for Quite Universal Circuit Simulator, is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit.

The Qucs cross-platform circuit simulator is a spin-off of Qucs. The letter S stands for the SPICE engine, which performs all simulations within the software. The Qucs subproject's goal is to integrate free SPICE circuit simulation kernels into the Qucs GUI. It combines SPICE's capability with the Qucs GUI's simplicity. Qucs utilizes its own SPICE incompatible simulation...
Electronic circuit design and simulation software list
QUCS – Quite Universal Circuit Simulator is a free simulation software developed on GNU/Linux environment. Well, this software really works on other operating systems such as Solaris, Apple Macintosh, Microsoft windows, FreeBSD, NetBSD etc. User can simulate large signal, small signal and noise behavior of the circuit using this simple circuit simulator.

Best Free Circuit Simulation software for Windows 10
If you don’t want to download an application then CircuitLab is what you need. It is an online circuit simulator and schematics tool. It doesn’t have all the bells and whistles unlike the previous two applications on our list, LTSpice, and NgSpice, but is an excellent alternative if you just want to make a basic circuit and simulate it.

  • How do dual-directional couplers behave with a mismatched load?
    If you can get s parameter model you can use that. There are also generic transformer and coupled line models so long as you've got a way of characterising it you should be able to model it. https://sourceforge.net/projects/qucs/. Source: over 1 year ago

  • I'm looking for an engineer to help me design a very basic comparison circuit for 2 batteries that will light an led if a battery is low while the other battery powers the load. $100 offered
    I need someone to design and point me to the correct parts for a circuit that will use 2, 5V LiPo batteries that are rechargeable, in a circuit that is built to run a memory bank. Basically a CMOS circuit, very low current draw. I need the LED indication to replace a battery. The switching between them has to be fast enough that the memory doesn't lose the program on it. $100 to the first person with a full parts... Source: 11 months ago
  • Is there a circuit simulation software? I'm very much a beginner.
    My go-to site for a quick simulation, and pretty schematics (that sounds almost NSFW) is circuitlab.com. Source: about 1 year ago
  • How to design preamp pedals?
    If you have a 10 band EQ pedal into a flat amp you can hear what these frequency shapes sound like. Once you understand what these preamps are doing, then you can learn about the electronic side, read the schematics, and start designing / playing with your own circuit mods / designs. A circuit simulator (like circuitlab.com) would be a good place to start doing that. Source: over 1 year ago
  • Is this circuit solving correct ?
    Tips if you want to check is circuitlab.com. Its very fast and easy to check. Source: about 2 years ago
  • Need some help here...
    I used circuitlab.com to simulate this behaviour, to obtain this image, which show what happens to the voltage across a capacitor when it is charged by passing a constant current through it. Noite that the slope (gradient) of the plot is constant during the entire time current is passing. Source: almost 3 years ago
