波数字滤波器（WDF）允许通过DSP对经典模拟电路进行高效的实时仿真。本文介绍了两种新的无能量双端口WDF适配器，允许混频波数字子网采用不同的极性和符号约定，并扩展了吸收的瞬时和稳态伪功率的定义的情况下，其中使用的主动符号约定。这一新的知识被应用到WDF双管放大器模型，它被证明是在一个更忠实的再现比以前的模型的模拟系统的结果。
Wave digital filters (WDFs) allow for efficient real-time simulation of classic analog circuitry by DSP. This paper introduces two new nonenergic two-port WDF adaptors that allow mixing wave digital subnetworks adopting different polarity and sign conventions and extends the definitions of absorbed instantaneous and steady-state pseudopower to the case in which the active sign convention is used. This new knowledge is applied to a WDF triode tube amplifier model and it is shown to result in a more faithful reproduction of the simulated system than the previous model.
