Abstract
To realize a compact device that detects phase or controls phase or an amplitude with high sensitivity, a signal controller includes: a linear conductor having a first end fixed to a negative electrode and a second end serving as a free end; a positive electrode facing the free end with a small gap therebetween; a first signal source that applies a voltage between the negative electrode and the positive electrode, the voltage applied being variable; a driving electrode that applies an electric field to a space around the conductor, the electric field having a component perpendicular to the lengthwise direction of the conductor; and a second signal source that applies an AC signal to the driving electrode. The signal processor can be a device for controlling or modulating phase or amplitude.

21. A signal processor for processing an AC signal, comprising:
-
a support conductor; a linear conductor having a first end fixed to the support conductor, the linear conductor vibrating in response to an AC electric field so as to have a displacement component perpendicular to a lengthwise direction of the linear conductor; a control electrode that applies the AC electric field to the linear conductor, the AC electric field having a component perpendicular to the lengthwise direction of the linear conductor; a detection electrode that detects a vibration signal generated as a result of the vibration of the linear conductor; a signal source that applies an AC signal to the control electrode; and an output unit that uses, as a processed signal obtained from the AC signal, information about the amplitude of the vibration signal detected by the detection electrode or the phase of the vibration signal. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
