Electromagnetic Oscillations and Waves

High-pass and low-pass filters with the FG module

Principle

A coil, a capacitor, an ohmic resistance and combinations of these components are investigated for their filter characteristics as a function of frequency. The phase displacement of the filters is determined also as a function of frequency.

Resistance, phase shift and power in AC circuits with digital function generator

Principle

Series circuits containing self-induc-
tances or capacitances and ohmic resi-
stances are investigated as a function
of frequency. Measuring the electrical
magnitudes with a work or power measure-
ment instrument, real ...

Induction impulse

Principle

A permanent magnet falls with different velocities through a coil. The change in the magnetic flux Φ generates an induced voltage impulse. The induced voltage impulse USS is recorded with a computer interface system. Depending on the polarity of the permane ...

Coupled resonant circuits

Principle

The Q factor of oscillating circuits is determined from the band width and by the Pauli method. In inductively coupled circuits (band-pass filters) the coupling factor is determined as a function of the coil spacing.
