Circuit Elements
An electronic circuit element used for generating waveforms within other apparatus is also described as a function generator, or waveform generator. A sub-system may provide an output proportional to some mathematical function of its input; for example, the output may be proportional to the square root of the input. Such devices are used in feedback control systems and in analog computers. An example is the Exar XR-2206 integrated circuit, which can generate sine, square, triangle, ramp, and pulse waveforms over a range of frequencies; it can be used in communications and instrumentation circuits, and also in a function generator instrument.

Famous quotes containing the words circuit and/or elements:
“Within the circuit of this plodding life
There enter moments of an azure hue,
Untarnished fair as is the violet
Or anemone, when the spring strews them
By some meandering rivulet, which make
The best philosophy untrue that aims
But to console man for his grievances.
I have remembered when the winter came,”
—Henry David Thoreau (1817–1862)
“Three elements go to make up an idea. The first is its intrinsic quality as a feeling. The second is the energy with which it affects other ideas, an energy which is infinite in the here-and-nowness of immediate sensation, finite and relative in the recency of the past. The third element is the tendency of an idea to bring along other ideas with it.”
—Charles Sanders Peirce (1839–1914)
