Filter theory

Coupling coefficient of resonators

The coupling coefficient of resonators is a dimensionless value that characterizes interaction of two resonators. Coupling coefficients are used in resonator filter theory. Resonators may be both electromagnetic and acoustic. Coupling coefficients together with resonant frequencies and external quality factors of resonators are the generalized parameters of filters. In order to adjust the frequency response of the filter it is sufficient to optimize only these generalized parameters. (Wikipedia).

Theramin Physics Demonstration - Nps Physics

The theremin contains two radio-frequency oscillators (or resonant circuits). This is called a "beat frequency oscillator" by physicists and "ring modulation" by some guitarists. One oscillator operates at a fixed frequency, usually about 285 kHz and the other varies between 282 and 285 kH

Amazing speed from Magnetic ball (300 000rpm)!!!

Brief principle of operation: 1. The generator creates pulses of about 10 Hz and transmits them to the coil. 2. The magnetic ball rotates in the coil from the pulses and creates an electromagnetic induction in the coil and feedback occurs with the generator. 3. With a slight increase in th

We show how Fourier series can be used to study ODEs that are forced by some periodic function. This allows us to analyse the response of mechanical systems when the forcing has a frequency close to the resonant frequency.
