Tugas 4 [Fatih Zaidan Aqil] Gerbang Logika
Gerbang Logika dan Aljabar Boolean
A. Konstanta Boolean dan Variabel
- Aljabar Boolean dibawah ini hanya mempunyai dua nilai : 0 dan 1.
- Logika 0 dapat dikatakan : false, off, low, no, saklar terbuka. Program Studi T. Elektro FT - UHAMKA Slide - 3 3
- Logika 1 dapat dikatakan: true, on, high, yes, saklar tertutup.
- Tiga operasi logika dasar: OR, AND, dan NOT
B. Tabel Kebenaran
- Sebuah tabel kebenaran menggambarkan hubungan antara input dan ouput sebuah rangkaian logika.
- Jumlah The number of entries corresponds to the number of inputs. For example a 2 input table would have 2 2 = 4 entries. A 3 input table would have 2 3 = 8 entries
C. Operasi OR dengan gerbang OR
The Boolean expression for the OR operation is X = A + B
- This is read as “x equals A or B.”
- X = 1 when A = 1 or B = 1.
D. OR Operation With OR Gates
The OR operation is similar to addition but when A = 1 and B = 1, the OR operation produces 1 + 1 = 1. - In the Boolean expression Program Studi T. Elektro FT - UHAMKA Slide - 3 7
- In the Boolean expression x=1+1+1=1 We could say in English that x is true (1) when A is true (1) OR B is true (1) OR C is true (1)
