A reauation method of the three-dimensional transfer functions

In this pape~ we propose a methd for mEng three dimensional transfer functions (3DTF) by the state-space method. If one extends the past methods for realizing two-dimensional transfer functions to 3DTF, complicated matrix calculation is necesary, or enormous equations have to be solved. Therefore, in this paper, we mlize denominator and numerator of the given 3DTF independently. By using this method, the abovementioned difliculties can be avoided.
