EE 350
PROBLEM SET 4
DUE: 30 September 2008
Reading assignment: Lathi Sections 2.3 and 2.4
Exam I
is scheduled for Thursday, September 25 from 8:15 pm to 10:15 pm in room 102 Forum for all sections. The
exam covers material problem sets 1 through 3, and laboratory #1. The exam is closedbook, but you may bring one
8 1/2 by 11 inch note sheet, Calculators are
not
allowed as graphical/scienti±c calculators are capable of graphing
functions and solving ODEs: skills that you must be capable of doing by hand.
Carefully read section 2.42 in the text which presents a graphical interpretation of convolution. This approach
yields signi±cant insight to the convolution operation and is an important tool that will be used in technical electives
such as Introduction to Communications (EE 360), DiscreteTime Systems Analysis (EE 351), and Fundamentals of
Digital Signal Processing (EE 453).
Recitations sections will meet during the week of September 22.
Problem 19:
(30 points)
In this problem you will use experimental data to estimate the capacitance and inductance used in Laboratory #1.
Using these estimated component values, you will compare the simulated and measured zerostate unitstep response
of the series RLC circuit for three diﬀerent values of series resistance.
1. (6 points) In problem 13 you determined that the risetime
t
r
of a ±rstorder system is related to the time
constant
τ
as
t
r
=
τ
ln(9)
.
This result can be used to predict the risetime, or estimate the time constant given the risetime. The latter
fact enables you to determine the value of the inductor and capacitor used in Laboratory #1. The MATLAB
