Errata for Part 1 lecture notes.
Page numbers based on the student version with Neuhoff #s, not Ulrich #s.

p.7
MS(x) = \sig^2(x) + M^2(x) has extra "(x)" in it.

p.8
samples of the image -> samples of the signal.

p.13 (Fact 5)
	"will be given in class or given as a homework problem" should be
	"will be left as an exercise."

p.14 (Fact 7)
	The sum of two periodic signals will be periodic
	if the ratio of their periods is rational
	OR if (one or both) of the signals is a constant signal.
	(And of course the "least common multiple" heuristic
	is not useful in the case of constant signals.)

p.15
top equation should not have the power of 2 in the exponent.

p.16
before "Fact 1," the sentence should end "for continuous-time signals"

p.18
y(t) = x(t) - 2 should be -2 outside of the support interval of x(t)

p.18
helpful to categorize "signal value operations" and "time operations"

p.44, problem 6
label tic marks

p.45, problem 8
``discrete-time signal'' rather than ``continuous-time signal''

p.46 problem 22
