A technique used to design infinite impulse response (IIR) digital filters from the squared magnitude function of a normal analog lowpass filter is presented in this paper.
本文提出了一种从模拟低通原型滤波器的振幅平方函数设计“无限脉冲响应(IIR)”数字滤波器的方法。
Applying the LVDT's output to a synchronous rectifier followed by a lowpass filter produces a dc voltage that can feed an ADC or directly drive an analog feedback-control system.
将LVDT输出加在同步稳压器上，跟随一个低通滤波器，产生直流电压送至adc或直接驱动模拟反馈控制系统。
When you need some analog outputs and you have an FPGA in your system, you probably choose to use a PWM module and a simple lowpass filter such as those in Figure 1.
当需要一些模拟输出和系统中有FPGA时，很可能选择使用如图1的PWM模块和简单低通滤波器。
