Frequency synthesizer — A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie… … Wikipedia
Frequency multiplier — A frequency multiplier is commonly used in a radio receiver or radio transmitter to multiply the base frequency of the oscillator by a predetermined number. This multiplied frequency is then amplified and sent to the final drive stage and into… … Wikipedia
Synthesis of noble metals — refers to the realization of the age old dream of alchemists to artificially produce noble metals. The goal of this could be to achieve greater economic gain when compared to traditional methods of obtaining noble metals. Synthesis of noble… … Wikipedia
Frequency modulation synthesis — In audio and music frequency modulation synthesis (or FM synthesis) is a form of audio synthesis where the timbre of a simple waveform is changed by frequency modulating it with a modulating frequency that is also in the audio range, resulting in … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
Synthesis — The term synthesis (from the ancient Greek Polytonic|σύνθεσις σύν with and θέσις placing ) is used in many fields, usually to mean a process which combines together two or more pre existing elements resulting in the formation of something new.… … Wikipedia
