NOR Gate using PNP BJTs

Question

Problem: NOR Gate using PNP BJTs. Solve this hands-on electronics task on EWskills.

Accepted Answer

Both PNP transistors must be ON to complete the pull-up path. Since a PNP transistor turns ON for a LOW input, Y becomes HIGH only when both inputs are LOW.

Y = (A + B)'
