77Dielectric spectroscopy — A dielectric permittivity spectrum over a wide range of frequencies. The real and imaginary parts of permittivity are shown, and various processes are depicted: ionic and dipolar relaxation, and atomic and electronic resonances at higher energies …
78Pierce oscillator — The Pierce oscillator is a type of electronic oscillator circuit particularly well suited for implementing crystal oscillator circuits. Named for its inventor, George W. Pierce (1872 1956), the Pierce oscillator is a derivative of the Colpitts… …
79Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
80Varistor — A 385 volt metal oxide varistor A varistor is an electronic component with a diode like nonlinear current–voltage characteristic. The name is a portmanteau of variable resistor. Varistors are often used to protect circuits against excessive… …
