Merakit rangkaian filter pasif

Melakukan penalaan rangkaian filter untuk mendapatkan respon frekuensi yangdiinginkan

Mengetahui respon band pass filter dan -3dB melalui pengukuran

II 'asar Te-ri

Filter adalah suatu rangkaian yang digunakan untuk membuang tegangan output pada

frekuensi tertentu. Untuk merancang rangkaian filter dapat digunakan komponen pasif

(R,,!" dan komponen aktif (#p-$mp, transistor". %engan demikian filter dapat

dikelompokkan men&adi filter pasif dan filter aktif. 'ada laporan ini hanya dibahas

mengenai filter pasif sa&a.

'ada dasarnya filter dapat dikelompokkan berdasarkan response (tanggapan"

frekuensinya men&adi &enis)

*. Filter lolos rendah+Low pass Filter.

. Filter lolos tinggi+High Pass Filter.

3.

Filter lolos rentang+Band Pass Filter.

. Filter tolah rentang+Band stop Filter or Notch Filter.

Untuk membuat filter seringkali dihindari penggunaan inductor, terutama karena

ukurannya yang besar. ehingga umumnya filter pasif hanya memanfaatkan komponen R

dan ! sa&a.

ebuah ,and75ass filtermerupakan perangkat yang meleatifrekuensi dalam kisaran

tertentu dan menolak ( attenuates " frekuensi di luar kisaran tersebut. !ontoh darianalog

elektronik band-pass filteradalah sirkuit R! (a resistor- induktor- kapasitorsirkuit ". Filter

ini &uga dapat dibuat dengan menggabungkan -pass filter rendahdengan-pass filter tinggi.Band pass filter digunakan terutama di nirkabel pemancar dan penerima. Fungsi utama filter

seperti di pemancar adalah untuk membatasi bandidth sinyal output minimum yang

diperlukan untuk menyampaikan data pada kecepatan yang diinginkan dan dalam bentuk

yang diinginkan. 'ada recei/er ebuah band pass filter memungkinkan sinyal dalam rentang

frekuensi yang dipilih untuk didengarkan, sementara mencegah sinyal pada frekuensi yang

tidak diinginkan.

*. Buatlah rangkaian seperti pada Gambar 1. Ukur tegangan di 5out kemudian atur

nilai kapasitr (!" agar 5out dapat maksimum di frekuensi *M7:. akukan haal

tersebut untuk tiga kapasitor yang tersedia (atur freskuensi resonansi di *M7:"

. 0emudian kembangkan rangkaian pada Gambar 1 men&adi seperti pada Gambar

2 dengan nilai ! yang masih sama. Ukurlah tegangan di 5out pada frekuensi)

*4407:, ;4407:, *M7:, *.;M7:. 0emudian !atat data hasil tersebut.

3. $tur kembali frekuens input di *M7: (frekuensi resonansi". 0embangkan lagi

rangkaian sebelumnya men&adi rangkaian seperti pada Gambar 3. $tur channel

.

0emudian ubah tampilan osiloskop ke dalam mode >?. $mati bentuk gelombang

tersebut dan gambarlah. 0emudian pindahkan chanel osiloskop untuk trace

5out. Masih dalam mode >? amati bentuk gelombang dan gambarlah. %ari

gambar tersebut dapat diketahuin frekuensi resonansinya.
