Transfer Function

A transfer function (also known as the system function or network function) is a mathematical representation, in terms of spatial or temporal frequency, of the relation between the input and output of a linear time-invariant system with zero initial conditions and zero-point equilibrium. With optical imaging devices, for example, it is the Fourier transform of the point spread function (hence a function of spatial frequency) i.e. the intensity distribution caused by a point object in the field of view.

Famous quotes containing the words transfer and/or function:

    If it had not been for storytelling, the black family would not have survived. It was the responsibility of the Uncle Remus types to transfer philosophies, attitudes, values, and advice, by way of storytelling using creatures in the woods as symbols.
    Jackie Torrence (b. 1944)

    The more books we read, the clearer it becomes that the true function of a writer is to produce a masterpiece and that no other task is of any consequence.
    Cyril Connolly (1903–1974)
