The act of approximating; a drawing, advancing or being near; approach; also, the result of approximating.
An approach to a correct estimate, calculation, or conception, or to a given quantity, quality, etc.
A continual approach or coming nearer to a result; as, to solve an equation by approximation.
a mathematical definition of the desired transfer function. Typically expressed as a rational polynomial, from which can be obtained a set of poles and zeros in the s-plane. An approximation can be achieved in many ways, including: synthesis: which I think of as being pure pencil and paper work, ending up with a solution in precise mathematical form CAD: which is what I have done, and which could never be done with pencil and paper alone; a computer is essential. ~~~~~ go back with your browser back button.

an approximate calculation of quantity or degree or worth; "an estimate of what it would cost"; "a rough idea how long it would take"
the quality of coming near to identity (especially close in quantity)
A mathematical quantity that estimates a desired quantity.
An approximation is an inexact representation of something that is still close enough to be useful. Although approximation is most often applied to numbers, it is also frequently applied to such things as mathematical functions, shapes, and physical laws.
