  In this work, the biquaternion Z transformation method is proposed to solve a
class of biquaternion recurrence relations. Biqueternion Z transform is an
natural extension of the complex Z transform. In the design process, special
norm presentation is employed to analyze the region of convergence of the
biquaternion geometry sequence. In addition, some useful properties have been
given. It is shown that the proposed properties is helpful to understand the
biquaternion Z transform. Finally, several examples have been given to
illustrate the effectiveness of the proposed design method.
