  2. Traf-O-Data - Wikipedia

    en.wikipedia.org/wiki/Traf-O-Data

    The real contribution of Traf-O-Data was the experience that Gates and Allen gained, skills they used to write Altair BASIC for the MITS Altair 8800 computer: "Even though Traf-O-Data wasn't a roaring success, it was seminal in preparing us to make Microsoft's first product a couple of years later.

  3. Fourier transform - Wikipedia

    en.wikipedia.org/wiki/Fourier_transform

    An example application of the Fourier transform is determining the constituent pitches in a musical waveform.This image is the result of applying a constant-Q transform (a Fourier-related transform) to the waveform of a C major piano chord.

  4. Abel transform - Wikipedia

    en.wikipedia.org/wiki/Abel_transform

    A geometrical interpretation of the Abel transform in two dimensions. An observer (I) looks along a line parallel to the x axis a distance y above the origin. What the observer sees is the projection (i.e. the integral) of the circularly symmetric function f(r) along the line of sight.

  5. Transformer - Wikipedia

    en.wikipedia.org/wiki/Transformer

    In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across any other coils wound around the same core.

  7. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    Single-phase distribution transformer in Canada. A distribution transformer or service transformer provides a final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. [1]
