Notes:

  • The designators "M," "W," "R," and "F" refer to the topic coverage on Monday, Wednesday, Thursday, and Friday, respectively, of that week.
  • The section numbers specified above refer to the 8th edition of the textbook by Ulaby and Ravaioli, but they should be the same for the 7th and 8th editions.
  • All supplemental readings are available at the course Moodle site.

Complex Arithmetic Examples

Several sets of problems involving complex numbers and variables are provided below to help you practice solving those types of problems. They will not be collected or graded. The problem sets and their solutions are available in separate files. All are in PDF format:

Note that the answer to Prob. 1 in the polar-to-rectangular section is incorrect; the imaginary part should be −0.96, not −0.096.

Please let me know if you discover any additional errors in either file.
