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)
“The Laws of Nature are just, but terrible. There is no weak mercy in them. Cause and consequence are inseparable and inevitable. The elements have no forbearance. The fire burns, the water drowns, the air consumes, the earth buries. And perhaps it would be well for our race if the punishment of crimes against the Laws of Man were as inevitable as the punishment of crimes against the Laws of Nature—were Man as unerring in his judgments as Nature.”
—Henry Wadsworth Longfellow (1807–1882)
