• Transfer function Wikipedia

    In engineering, a transfer function (also known as system function or network function) of an electronic or control system component is a mathematical function which theoretically models the device's output for each possible input. In its simplest form, this function is a two-dimensional graph of an independent scalar input versus the dependent scalar output, called a transfer curve or

    Carbon filtering Wikipedia

    Linear filter Wikipedia

    Linear filters process time-varying input signals to produce output signals, subject to the constraint of linearity.In most cases these linear filters are also time invariant (or shift invariant) in which case they can be analyzed exactly using LTI ("linear time-invariant") system theory revealing their transfer functions in the frequency domain and their impulse responses in the time domain.
