Coupled resonant circuits

Item no.: P2450201 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. Tasks Determine the dissipation factor t and k and the quality factor Q from the band
