biquadratic function meaning in English

双二次函数

In this paper , the principles on vlsi realization of one - dimension cwt are expounded , and the relevant methods of the implementation are classified and compared with each other . and then , a novel method of implementing one - dimension continuous wavelet transform using switched - current circuit is proposed , in which the continuous wavelet transform is implemented by the parallel structure of biquadratic functions realized with switched - current circuits on the basis of approximation theory of network function
