#   		Assigned Due Returned Problems Assigned
(In Sedra & Smith unless otherwise noted)
12

12/05 12/10 12/13   Read Chapter 5, Section 5.1
  Do +5.1, 5.3, +5.4, 5.5, +5.6
 
  Note errata on problem +5.1
11

11/19 12/05 12/08   Read 4.10, 4.11
  Do 4.105, +4.106, +4.115, +4.116
10

11/05 11/19 11/24   Read 4.8, 4.9
  Do 4.90, +4.91, 4.94, +4.96, 4.97, D4.98, +D4.99
 
  Hint for 4.90: There is enough information to
  compute the overdrive voltage. From this you
  can determine the region of operation even
  though you do not know the threshold voltage.
 
  (Also study for the test on Wednesday, 11/12.)
9

10/29 11/5 11/12   Review 4.7
  Do +4.85, 4.86
 
  Note: In 4.86 the coaxial cable is just a
  (fancy) wire. There is no connection from the
  center conductor to the shield. For the
  calculations needed in this problem the coaxial
  cable may be replaced with an ordinary wired
  connection. However, if such a coaxial cable
  is used, then there are advantages if Ri2 = 50 ohms
  by design. This will be discussed further in class.

  Note errata on 4.86.
8

10/22 10/29 10/31   Read Sections 4.6, 4.7
  Do *4.67, 4.74, 4.77, 4.78, +4.79, D4.80 (As
  part of D4.80, also do Ex 4.30 and Ex 4.32.)
 
  See this note on 4.78.
7

10/15 10/22 10/27   Read Sections 4.3, 4.4, 4.5 in Chapter 4
  Do +D4.34, +4.46, *4.47, 4.49, +4.51, D4.55,
  +D4.65     Also note errata on these problems:
  +D4.34, +4.46 problem statement,
  +4.46 answer, 4.49, +D4.65
 
  Note: On 10/16 at 10:47 AM a typographic error in this
  assignemnt was corrected. The first problem in the list
  was changed from "+D3.34" to "+D4.34."
6

10/01 10/15 10/17   Read Chapter 4 through Section 4.2
  Do 4.1, +4.4, +4.11, +4.12, 4.18, +4.20, *4.33
  Note errata on 4.18 part (a).
  Reminder: Study for test on Wednesday, 10/8.
5

9/24 10/01 10/06
  Review Chapter 3
  Do 3.4 parts c, g, h only, +3.41, 3.49, 3.54
  3.55, +3.85, **3.105 Also assume C is charged
  so that it is operating in the steady state.
  Hint: These diode circuits can be quickly
  built and tested in the lab or simulated in
  PSpice. (E.g. use 1N4004 diodes in the lab or
  an ideal diode model in PSpice along with
  25 kohms resistors and 1 µF non-polarized
  capacitors. If you simulate the circuits, let
  the stop time in the transient command be much
  greater than one period of the signal. E.g.
  use 200 ms.)
 
  Note: 3.54 and 3.55 can be done in lab on 9/24.
  Note this remark on +3.85.

9/17 9/24 9/26
  Review Ch 2, Review Sec. 3.1 through 3.5,
  Read 3.6 through 3.9
 
  Do *2.77 (recall biamp technique), 2.98, D*2.99
  3.4 parts i, j, k only, +3.18, *3.32, 3.78,
  D3.99, +3.114
 
  Note errata on the answer to +3.78.
  Note errata on the answer to +3.114.
  Also see this remark on *2.77.

9/10 9/17 9/19
  Read 2.3 through 2.9, and 3.1 through 3.5
 
  Do *2.43, D2.51, +2.62, +2.73, +3.2,
  3.4 parts a, b, f only (mathcad or matlab is
  recommended), +3.9, +D3.15 (mathcad is
  recommended), +3.37, +3.67, +3.76
 
  Note errata on the answer to +3.9.

  Note errata on the answer to +D*1.9

Note 1) Discussion in class is an inportant part of working the assignments. Students must be prepared to discuss the assignments starting with the class following the "Assigned" date.

Note 2) The text includes "Excercises" embedded throughout the reading assignments and "Problems" at the end of each chapter. All the assignments refer to "Problems" at the end of the chapter unless they are prefixed with "Ex". Example: Ex1.5 is found on page 10 but 1.5 is found on page 51.

Note 3) A "+" mark in front of the problem number means an answer is given in the text, in Appendix H.

Note 4) The letter "D" in front of a problem number indicates a design oriented problem. The student may need to use some judgement in undertanding what the problem statement is requesting. (Ask Prof. De Boer if you are in doubt.)

Note 5) Asterisks (*) indicate more difficult or more time-consuming problems (in the authors' judgement). The more asterisks, the more difficult.

Note 6) If the "Returned" date is a link, then the solution key is posted on courses@dordt.

Note 7) Problem sets shown above with no "Assigned" date are tentative. More problems might be added, expected due dates might change, but problems shown will eventually be assigned.

Note 8) If you are having difficulty reading the latest version of this page it may have to do with your browser's cached memory. Read this note on cached pages to solve the problem.

Note 9) If a link brings you to a login page use your Dordt College Groupwise username and password. If this brings you to the opening page of courses@dordt instead of the resource you wanted, click your browser's back arrow twice to return to the link on this page, then click the link again. Now that you are signed in the link will work properly.
