  2. Capacitance - Wikipedia

    en.wikipedia.org/wiki/Capacitance

    Stray capacitance can allow signals to leak between otherwise isolated circuits (an effect called crosstalk), and it can be a limiting factor for proper functioning of circuits at high frequency. Stray capacitance between the input and output in amplifier circuits can be troublesome because it can form a path for feedback, which can cause ...

  3. Dielectric spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Dielectric_spectroscopy

    Electrochemical impedance spectroscopy can be used to obtain the frequency response of batteries and electrocatalytic systems at relatively high temperatures. [ 34 ] [ 35 ] [ 36 ] Biomedical sensors working in the microwave range relies on dielectric spectroscopy to detect changes in the dielectric properties over a frequency range, such as non ...

  4. Symbolic circuit analysis - Wikipedia

    en.wikipedia.org/wiki/Symbolic_Circuit_Analysis

    Symbolic circuit analysis is a formal technique of circuit analysis to calculate the behaviour or characteristic of an electric/electronic circuit with the independent variables (time or frequency), the dependent variables (voltages and currents), and (some or all of) the circuit elements represented by symbols. [1] [2]

  5. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    As shown in the graph, the higher capacitance values can fit the lower frequencies better while the lower capacitance values can fit better the higher frequencies. Aluminum electrolytic capacitors have relatively good decoupling properties in the lower frequency range up to about 1 MHz due to their large capacitance values.

  6. Signal generator - Wikipedia

    en.wikipedia.org/wiki/Signal_generator

    A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.

  7. Miller effect - Wikipedia

    en.wikipedia.org/wiki/Miller_effect

    In this example, the frequency ω 3dB such that ω 3dB C M R A = 1 marks the end of the low-frequency response region and sets the bandwidth or cutoff frequency of the amplifier. The effect of C M upon the amplifier bandwidth is greatly reduced for low impedance drivers ( C M R A is small if R A is small).

  8. Spectrogram - Wikipedia

    en.wikipedia.org/wiki/Spectrogram

    A common format is a graph with two geometric dimensions: one axis represents time, and the other axis represents frequency; a third dimension indicating the amplitude of a particular frequency at a particular time is represented by the intensity or color of each point in the image.

  9. Pierce oscillator - Wikipedia

    en.wikipedia.org/wiki/Pierce_oscillator

    The total capacitance seen from the crystal looking into the rest of the circuit is called the "load capacitance". When a manufacturer makes a "parallel" crystal, a technician uses a Pierce oscillator with a particular fixed load capacitance (often 18 or 20 pF) while trimming the crystal to oscillate at exactly the frequency written on its package.
