Abstract
An input signal is supplied to a first port of a non-reversible circuit and those frequency components of the input signal applied to a second port of the non-reversible circuit which differ from the resonance frequency of a resonance element connected to the second port are absorbed by a resistive terminating element connected to the second port. On the other hand, a frequency component of the input signal which coincides with the resonance frequency is derived at the third port of the non-reversible circuit. By changing the resonance frequency of the resonance element, the frequency component of the input signal which are provided to the third port can be altered.
