== Circuit elements ==

===Waveform generator===
An electronic circuit element used for generating waveforms within other apparatus that can be used in communications and instrumentation circuits, and also in a function generator instrument. Examples are the [[Exar Corporation|Exar]] XR2206<ref>{{cite web |url=http://www.jameco.com/Jameco/Products/ProdDS/34972.pdf |publisher=Exar |title=''Exar XR-2206 Monolithic Function Generator'' |access-date=16 June 2013}}</ref> and {{citation needed span |date=January 2019 |reason=The previous source, Intersil’s own datasheet, doesn’t support the claim that ICL8038 was ever used in function generators as they are described in this article. |text=the [[Intersil ICL8038]] integrated circuits}}, which can generate sine, square, triangle, ramp, and pulse waveforms at a [[Voltage-controlled oscillator|voltage-controllable frequency]].

===Function generator===
An electronic circuit element that provides an output proportional to some mathematical function (such as the square root) of its input; such devices are used in [[feedback control]] systems and in [[analog computer]]s. Examples are the [[Raytheon]] QK329 square-law tube<ref>{{cite web |url=http://www.radiomuseum.org/forumdata/users/6435/file/varie/QK329_App.pdf |last1=Miller |first1=Joseph A. |last2=Soltes |first2=Aaron S. |last3=Scott |first3=Ronald E. |publisher=[[Electronics (magazine)|Electronics]] |date=February 1955 |title=''Wide-band Analog Function Multiplier'' |access-date=15 June 2013}}</ref> and the Intersil ICL8048 Log/Antilog Amplifier.<ref>{{cite web |url=http://www.intersil.com/content/dam/Intersil/documents/fn28/fn2864.pdf |publisher=[[Intersil]] |title=''Intersil ICL8048 Log Amplifier'' |access-date=16 June 2013}}</ref>
