Gerbang Logika XOR

Gerbang Logika XOR

Gerbang logika ini hanya akan mengeluarkan hasil output bernilai 1 jika hanya salah satu input saja yang bernilai 1. Maksudnya jika kedua input bernilai 1, maka hasil output-nya tetaplah 0.

KESIMPULAN : Jika Semua Input bernilai SAMA maka Output logika bernilai 0, Output akan benilai 1 jika input yang dimasukkan BERBEDA.output akn belogika 1 jika input berlogika ganjil,dan output akn berlogika 0 jika input berlogika genap.

Ket :     A   = Input Switch

            B   = Input Timer

            C   = Input light sensor

            C’  = Komplemen C (logika NOT)

            Q1 = Output logika AND dari C’ dan B

Q 2 = Output logika Q1 + A
