The most widely used is linear, time-invariant digital filters, and IIR and FIR filters.───应用最广的是线性、时不变数字滤波器，以及IIR和FIR滤波器。
For the lowpass filter example above, you have a choice of two FIR and four IIR digital filter designs.───对于上面的例子提及的低通滤波器，你可以选择两种FIR和四种IIR数字滤波器进行设计。
In this thesis, we will discuss the theory of the realization of difference equations in designing IIR and FIR of digital filters.───讨论数字滤波器在采用差分方程实现中的IIR和FIR设计中所涉及的理论支持。
This paper introduces the design and implementation of a universal FIR/IIR filter, which is used in the servo system with digital solution instead of primary PID closed loop control mode.
