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.
The Roland Micro Cube, left, a small and portable digital modeling amplifier. Digital amp modelers Standalone modeling devices such as the Line 6 POD and Fractal Axe-FX digitize the input signal and use a DSP, a dedicated microprocessor, to process the signal with digital computation, attempting to achieve the sound of expensive professional amplifiers in a much less costly and more compact ...
Probably the best known digital simulators are those based on Verilog and VHDL. Some electronics simulators integrate a schematic editor, a simulation engine, and an on-screen waveform display (see Figure 1), allowing designers to rapidly modify a simulated circuit and see what effect the changes have on the output. They also typically contain ...
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]
More modern IF amplifier and demodulator in integrated circuit form Intermediate-frequency (IF) amplifiers are amplifier stages used to raise signal levels in radio and television receivers, at frequencies intermediate to the higher radio-frequency (RF) signal from the antenna and the lower (baseband) audio or video frequency that the receiver ...
Demodulation is the process of extracting the original information-bearing signal from a carrier wave. A demodulator is an electronic circuit (or computer program in a software-defined radio) that is used to recover the information content from the modulated carrier wave. [1] There are many types of modulation, and there are many types of ...
The product demodulator has some advantages over an envelope detector for AM signal reception. The product demodulator can decode overmodulated AM and AM with suppressed carrier. A signal demodulated with a product detector will have a higher signal-to-noise ratio than the same signal demodulated with an envelope detector.
GNU Circuit Analysis Package (Gnucap) is a general purpose circuit simulator started by Albert Davis [1] in 1993. [2] It is part of the GNU Project. [3] The latest stable version is 0.35 from 2006. The latest development snapshot (as of July 2023) is from June 2023 and is usable.
