FAQs:

 

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

A. Three hours in lecture and at least six hours outside of class on homework, reading and review. Some of the homework hours will be scheduled in the evenings to make it easier and will be done in teams.

 

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. Attend all homework lab sessions. 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 lab homeworks about?

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

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.

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 .
