Embodiment Construction
[0060] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0061] The inventors of the present invention have found that: when a sine (or cosine) signal of a certain frequency passes through the linear first-order inertia link, the output signal of the linear first-order inertia link is a sine (or cosine) signal with the same frequency as the input signal, but the output The phase and amplitude of the sine (or cosine) signal will change, and the amount ...
