Lecture Assignment 0b

Due at the start of class, Tuesday, October 19.

Please submit answers to these questions either as a hard copy (typeset or handwritten are OK) or by email to jteresco AT by the start of class. We will discuss these questions at the start of class, so no late submissions are accepted.

  1. We constructed a NAND gate from two transistors in series. What function of three inputs is obtained by placing three transistors in series?
  2. Show that the NOR gate is universal by building circuits to compute NOT, AND, and OR using only NOR gates.
