(a) NAND-NOR_t-shoot_cRangkaian salah

Dilihat dari 2 contoh rangkaian diatas. Terdapat masalah pada gate 7408. Karena jika dilihat dari truth table seharusnya ketika input A: 0, B: 0, dan C: 1 maka output yang dihasilkan akan high. Dimana dapat dilihat dari probe yang akan menyala. Tetapi pada kasus diatas probe tidak menyala.

(b) Gate mengalami trouble. Karena logika untuk OR (1,0) outputnya 1. NAND-NOR_t-shoot_d

Dari tabel kebenaran seharusnya input ( 1,0,1) output 1. Tetapi karena gate 7432 trouble maka probe tidak menyala (bukan berarti error)Rangkaian setelah diperbaiki

Terbukti gate tidak error. Setelah diganti lampu menyala.
