WebMay 22, 2024 · 11.7.1: Multiple-Feedback Filters. The basic multiple-feedback filter is a second-order type. It contains two reactive elements as shown in Figure . One pair of elements creates the low-pass response , and the other pair creates the high-pass response . Because of this, the ultimate attenuation slopes are dB. WebAug 10, 2024 · Definition: The filter circuit which allows only low pass frequency components and blocks all other higher frequency components is called a low pass filter. The name LPF itself indicates low range frequency. This type of filter circuit allows the frequency components of the signal less than the cut of the frequency range of a signal.
