Synthesis

Synthesis (from the ancient Greek , σύν (with) and θεσις (placing)), is commonly understood to be an integration of two or more pre-existing elements which results in a new creation.

Philosophical synthesis
The term is broad in meaning and can apply to physical, ideological, and/or phenomenological entities. In dialectics, synthesis is the final result of attempts to reconcile the inherent contradiction between thesis and antithesis. Along with the similar concept of integration, synthesis is generally considered to be an important element of modern philosophy, particularly in the various emerging ideas often considered to be holistic (as opposed to reductionistic).

Chemical synthesis
In chemistry, chemical synthesis is the process of forming a particular molecule from chemical reagents.

Synthesis in electronics and acoustics
In electronic music, sound synthesis is any of a number of methods of sound generation that a piece of hardware or software may employ, e.g. subtractive synthesis or FM synthesis. Modern electronic keyboard instruments are based on digital sound synthesizers that create audio waveforms that sound like they came from a violin, for example, without an actual violin, because the sound is synthesized to emulate the violin waveform patterns.

A video synthesizer electronically creates TV signals without necessarily requiring the use of a TV camera. Moving abstract patterns, text subtitles, colorized or processed camera images can all be in the output of a video synthesizer. Analog video synthesizers included the Sandin Image Processor, the Rutt-Etra, Steve Beck's "Beck Direct" Synthesizer, Bill Hearn's colorizer, and the seminal work of Nam Jun Paik. Early digital synthesizers included Stephen Beck's Video Weavings, the 2901 bit slice processor from Steina and Woody Vasulka with Schier and Dosch, Sandin's Digital Image Colorizer, Etra's "Kangaroo Giant Box" , and the Fluidigeo Synthesizer. Documentation on the history of video synthesizers can also be found at.

In the world of electronic design automation, (logic) synthesis is the process of converting a digital design written in a hardware description language (HDL) into a low-level implementation consisting of primitive logic gates. Most large integrated circuits designed today are written in an HDL and "compiled" using a (logic) synthesis product.
