For the beginner Chapter 1 gives you the basic information you need to use this system. Chapter 2 provides greater detail on the hardware and on how to upgrade your system. Your system is quite simple to set up. However if you are unsure of yourseff, find an experienced PC hand to ...
5.1 Detection,amplification and filter circuitsThe detection circuit of the tool monitor is driven by aconstant voltage 10 V or 12 V.Due to the condition thatthe resultant change of a small cutting force will be evensmaller,and the fact that the detector cannot be placedat the cutting ...
Further, it is ideal that the operation corresponding to the decay of the vibration of the string STR in the tone synthesizing portion is provided by setting the multiplication coefficients of the phase inversion circuits 34 and 38 corresponding to the bridge to a slightly larger value than -1....
