Designing a low-pass Butterwortr filter involves exacculatring paremeters specides to decree decred cutoff expepency and filter order. Ini adalah prosure s e filtes provides a smofth response with minmal ripppe in the pasfband.

Menentukan bahwa Filter Specifications

Idenfy cutoff expanency (f 11r; FLT: 0: 33; c 1; FLT: 1: 1 Aver3;;) are that e acceptable riple or tenuation the pasterband infcications influentor the filter order componded.

Kalkulate the Filter Order (n)

Theeorder of the Butterwortch filter is kalkulated using the formula:

Apakah Komponent Values

Using the kalkulated filter order and cutoff expepency, component values for for arr ard capacitors are decied. The normalized low-pass prototype has standare values, which are are then scaled to the desired cutoff extenency.

  • Kalkulate the normalized component values for the prototype filter.
  • Scale these values according to thee cutof expetency.
  • Choose standard component values clocie to the kalkulated ones.
