JENIS-JENIS GERBANG LOGIKA (LOGIC GATES)

Gambar
 Gerbang Logika ( Logic Gates )      Gerbang Logika ( Logic Gates ) adalah sebuah entitas untuk melakukan pengolahan input-input yang berupa bilangan biner (hanya terdapat 2 kode bilangan biner yaitu, angka 1 dan 0) dengan menggunakan Teori Matematika Boolean sehingga dihasilkan sebuah sinyal output yang dapat digunakan untuk proses berikutnya. Pengertian Gerbang Logika ( Logic Gates ) berdasarkan wikipedia : "Gerbang logika atau gerbang logik adalah suatu entitas dalam elektronika dan matematika Boolean yang mengubah satu atau beberapa masukan logik menjadi sebuah sinyal keluaran logik. Gerbang logika terutama diimplementasikan secara elektronis menggunakan diode atau transistor, akan tetapi dapat pula dibangun menggunakan susunan komponen-komponen yang memanfaatkan sifat-sifat elektromagnetik (relay), cairan, optik dan bahkan mekanik."    JENIS-JENIS GERBANG LOGIKA (LOGIC GATES)    7 jenis gerbang logika : * Gerbang AND : Apabila semua / salah ...

KOMPONEN ELEKTRONIKA (AKTIF DAN PASIF)

Gambar
KOMPONEN ELEKTRONIKA   ( PASIF DAN AKTIF )   Peralatan Elektronika adalah sebuah peralatan yang terbentuk dari beberapa Jenis Komponen Elektronika dan masing-masing Komponen Elektronika tersebut memiliki fungsi fungsinya tersendiri di dalam sebuah Rangkaian Elektronika. Seiring dengan perkembangan Teknologi, komponen-komponen Elektronika makin bervariasi dan jenisnya pun bertambah banyak. Tetapi komponen-komponen dasar pembentuk sebuah peralatan Elektronika seperti Resistor, Kapasitor, Transistor, Dioda, Induktor dan IC masih tetap digunakan hingga saat ini. Berikut ini merupakan Komponen Elektronika dasar yang sering digunakan. A. Resistor Resistor atau disebut juga dengan Hambatan adalah Komponen Elektronika Pasif yang berfungsi untuk menghambat dan mengatur arus listrik dalam suatu rangkaian Elektronika. Satuan Nilai Resistor atau Hambatan adalah Ohm (Ω). Nilai Resistor biasanya diwakili dengan Kode angka ataupun Gelang Warna yang terdapat di b...
