PURPOSE: To improve the flexibility of control or optimization while assembled serial structure is kept by providing plural bypass switches which can functionally short-circuit at least one of elements. CONSTITUTION: The phase shift cells of a signal processing assembled serial system are realized in the form of plural integrated resistors r1-rN where the integrated elements (resistor R in special case) of an RC network deciding a center frequency are in series. Integrated bypass switches S1-SN are connected to the partial elements in parallel. In can be controlled by an operator by programming or selection from a control panel. Thus, the cutoff of the respective cells in the cell assembled serial system, namely, the center frequency can individually be optimized. |
