  2. Hartley oscillator - Wikipedia

    en.wikipedia.org/wiki/Hartley_oscillator

    Hartley oscillator using a common-drain n-channel JFET instead of a tube.. The Hartley oscillator is distinguished by a tank circuit consisting of two series-connected coils (or, often, a tapped coil) in parallel with a capacitor, with an amplifier between the relatively high impedance across the entire LC tank and the relatively low voltage/high current point between the coils.

    en.wikipedia.org/wiki/Discrete_Hartley_transform

    Formally, the discrete Hartley transform is a linear, invertible function H: R n → R n (where R denotes the set of real numbers).The N real numbers x 0, ..., x N−1 are transformed into the N real numbers H 0, ..., H N−1 according to the formula

  6. Leeson's equation - Wikipedia

    en.wikipedia.org/wiki/Leeson's_equation

    The common misunderstanding, that P s is the oscillator output level, may result from derivations that are not completely general. In 1982, W. P. Robins (IEE Publication "Phase noise in signal sources") correctly showed that the Leeson equation (in the −20 dB/decade region) is not just an empirical rule, but a result that follows from a ...

  8. Hartley transform - Wikipedia

    en.wikipedia.org/wiki/Hartley_transform

    In mathematics, the Hartley transform (HT) is an integral transform closely related to the Fourier transform (FT), but which transforms real-valued functions to real-valued functions. It was proposed as an alternative to the Fourier transform by Ralph V. L. Hartley in 1942, [ 1 ] and is one of many known Fourier-related transforms .

  9. Center tap - Wikipedia

    en.wikipedia.org/wiki/Center_tap

    A common application of this is in the Hartley oscillator. Inductors with taps also permit the transformation of the amplitude of alternating current (AC) voltages for the purpose of power conversion, in which case, they are referred to as autotransformers, since there is only one winding. An example of an autotransformer is an automobile ...
