Resonator Resonator A resonator is a device or system that exhibits resonance or resonant behavior, that is, it naturally oscillates at some frequencies, called its resonant frequencies, with greater amplitude than at others. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. A cavity
Greater-than sign greater-than sign (>) is an original ASCII character (hex 3E, decimal 62). The character in Unicode is ; this is inherited from the same value in ASCII. Apart from this, Unicode also has the following variants: The greater-than sign is used for an approximation of the closing angle bracket (⟩). ASCII does not have angular brackets. BASIC and C-family languages, (including Java and C++) use the operator > to mean "greater than". In Lisp-family languages, > is a function used to mean "greater than". In Coldfusion and Fortran, operator .GT. means "greater than". The double greater-than sign (») is used
