### Exam 2 Coverage: Primarily Text Chapter 4, Homeworks 6-7. The
primary topic covered is the Fourier Transform, properties and
pairs. Only a single handwritten two-sided crib sheet is allowed
for this exam, in addition to the textbook (open book) No
calculators. A table of Fourier Transform properties will be
attached to the exam, with the j notation removed and some
additions (e.g. Duality property) relative to Table 4.1 in the
textbook.
