Lecture Assignment 03

Due at the start of class, Thursday, September 16.

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

1. True or false: The signed product of two signed n-bit numbers can always be correctly expressed as a signed 2n-bit number. Justify your answer.

Note: the other problem that previously occupied this space has been postponed and will be part of the next lecture assignment.
