Noise control is an active or passive means of reducing sound emissions, often for personal comfort, environmental considerations, or legal compliance. Active noise control is sound reduction using a power source. Passive noise control is sound reduction by noise-isolating materials such as insulation, sound-absorbing tiles, or a muffler rather ...
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 later requires a separate program to provide that feature, such as Qucs-S, [ 1] Oregano, [ 2 ...
Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software allows for the modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many colleges and universities use this type of software for the teaching ...
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals or sound power level is ...
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] Though it is freeware, [ 4][ 5] LTspice is not artificially restricted to limit its ...
Aldec. VHDL-1987,-1993,-2002,-2008,-2019 V1995, V2001, V2005, SV2009, SV2012, SV2017. Active-HDL is Aldec's Windows-based simulator with complete HDL graphical entry and verification environment aimed at FPGA and SoC FPGA applications. Riviera-PRO is Aldec's Windows/Linux-based simulator with complete verification environment aimed at FPGA, SoC ...
In electronics, noise is an unwanted disturbance in an electrical signal. [ 1]: 5. Noise generated by electronic devices varies greatly as it is produced by several different effects. In particular, noise is inherent in physics and central to thermodynamics. Any conductor with electrical resistance will generate thermal noise inherently.
Noise calculation. Noise calculation is the process of calculating the level of noise immission using the metric dB (A). Noise immission is created by noise sources (noise emission) of various types which are propagating noise into the environment. A single source will create a certain level of immission primarily driven by originating sound ...
