<p>PURPOSE:To enable simulation of every vibration condition of a secondary vibration model in a simple circuit scale by providing a coefficient calculation part which calculate a coefficient via table readout. CONSTITUTION:A coefficient calculation part 11 is provided with tables 22, 23 (storing data for calculating a and b) with gamma<2> as an address. When gamma is a real number, the positive address area (gamma<2>>=0) of the tables 22, 23 is referred and reversely the negative address area (gamma<2=0) of the tables 22, 23 is referred, when gamma is an imaginary number. Therefore, a processing equivalent to complex calculation can be executed via a simple circuit constitution. Thus, a secondary vibration model can be simulated in all cases via a stable and simple circuit constitution.</p> |
