ABSTRACT:
In a filter circuit, resonators is connected in parallel between input and output terminal, an input signal is input through the input terminal and supplied to the resonators. Signal generators are connected to the resonators to control the resonators. The signal generators are controlled by a control unit so that the resonators are resonated to generate resonance signals at different resonant frequencies and at predetermined resonance phases. Thus, the output signal is set within a desired frequency range.
