Instructors: Prof. Dimitra Psychogiou and  Zoya Popovic

 

Weekly update, March 11th, 2017:

 

-          Practice problems for midterm: PracticeProblems-2420-S2017.pdf

-          The midterm will be held in class on Monday, March 13th. Extra office hours will be held from 5-6pm on Saturday (Prof. Popovic)

-          The exam is closed everything, no calculators. You can make 1 sheet with 10 equations – you pick. You need to turn in the sheet with your exam.

-          Here is a sample midterm: Midterm-practice.pdf

-          There is a lab at noon-2pm, we will learn a bit more about amplifiers, discuss HW9 and start putting the boards together. This is all you need for HW9, we will print out and give you the lab on Monday: HW9-ECEN2420-S2017-1.pdf

FAQs:

 

Q: How much time per week do I need to spend on this class?

A. One hour in lecture, 4 hours in lab and at least 4 hours outside of class on homework, reading and review.

Q: Is there a textbook for the course?

A. Yes. There is a paperback version.

Q: What will I know after the class that I do not know now? 

A. You will know how analog components work and how they are connected into simple and then more complicated circuits.

Q: What does “student participation” mean?

A. Read book in advance and be able to discuss material in class and in homework sessions. There will also be occasional participation assignments.  

Q: What will the homeworks look like?

A. Homeworks will be based on material from the textbook and occasionally from outside reading handouts which will be provided.

Q: What are the labs about?

A. Building a radio part by part, and then putting it together and demonstrating transmission and reception.

Q. Will we build the entire radio (with >200 parts) at once?

A: No, there are 8 separate small circuit boards that can be separately tested before they are inserted into a motherboard. These make up the following separate labs:

1.      Measure diode detector and get used to equipment, battery (2 lab sessions)

2.      Harmonic filter (1 lab session)

3.      IF filter (2)

4.      Switches (2)

5.      Transformers (1)

6.      Buffer, driver, filter, PA (3)

7.      VFO (2)

8.      AGC (2)

9.      Mixer, receive (1)

10.  Mixer, transmit (1)

11.  Mixer, BFO (2)

 

 

 

Standard rules:

 

Policies and Regulations:  The following policies and regulations apply for this course.

 

Honor Code. All students of the University of Colorado at Boulder are responsible for knowing and adhering to the academic integrity policy of the institution.

All incidents of academic misconduct shall be reported to the CU Honor Code Council (honor@colorado.edu, 303-725-2273). Students who are found to be in violation of the academic integrity policy will be subject to both academic sanctions from the faculty member and non-academic sanctions (including but not limited to university probation, suspension, or expulsion).

The instructor reserves the right to use anti-plagiarism software to help determine the originality of term papers.

 

Cell phones and PDAs. Out of respect for the students and instructors as well as to minimize interference to laboratory measurement it is mandatory that cell phones or other devices with annunciators or other disturbing audio capabilities be turned off before entering the classroom or laboratory. Calculators may be used during exams, but personal digital assistants or other devices with communications capabilities are not permitted.

 

Electronic Communication. Questions on the course material, schedule, or policies may be e-mailed to the instructors at the above-listed addresses. E-mailed questions will be addressed as soon as possible, although given the volume of e-mail received by the instructors a delay of up to several days may occur. All course-related e-mails should include the course number in the subject line.  Voice mailed questions will be handled similarly but with e-mailed responses.

 

Disability. Students who qualify for accommodations because of a disability should submit to the instructors a letter from CU Disability Services in a timely manner so that needs can be addressed.  Disability Services determines accommodations based on documented disabilities.  Contact: 303-492-8671, Willard 322, or http://www.colorado.edu/disabilityservices .
 
Religious Observances. Campus policy regarding religious observances requires that faculty make every effort to reasonably and fairly accommodate all students who, because of religious obligations, have conflicts with scheduled exams, assignments or required attendance. Conflicts between scheduled course activities and religious observances should be made known in writing to the instructors at least two weeks in advance of the activity so that alternate arrangements can be made. See full details at http://www.colorado.edu/policies/fac_relig.html .
 
Discrimination and Harassment. The University of Colorado at Boulder policy on Discrimination and Harassment (http://www.colorado.edu/policies/discrimination.html), the University of Colorado policy on Sexual Harassment, and the University of Colorado policy on Amorous Relationships applies to all students, staff and faculty.  Any student, staff or faculty member who believes s/he has been the subject of discrimination or harassment based upon race, color, national origin, sex, age, disability, religion, sexual orientation, or veteran status should contact the Office of Discrimination and Harassment (ODH) at 303-492-2127 or the Office of Judicial Affairs at 303-492-5550.  Information about the ODH and the campus resources available to assist individuals regarding discrimination or harassment can be obtained at http://www.colorado.edu/odh .
