Here is the block diagram and frequency response (Java Applet). You can change the value of elements by double-clicking. If this applet looks something weird, please reload it. The pickup moves 60dB, that is as much as 1,000 um (1 mm) by 1V of the input according to the frequency response at low frequencies. This does not meet our requirement at all. Therefore we set the servo to make it!! Quiz 1 What's going to happen if you increase the spring stiffness (K)?? Hint: You may change the value by double-clinking the element "K/m". Here is the answer. Let's set the servo to make it!! This class is produced by DIGITALFILTER.COM and Ueno Design Factory
