Study Questions #3: SYD Basics, Additive Synthesis, and the Simple Bell Patch

Before you answer these questions, you should have reviewed the required reading for this session (including LINKS listed in the Class Schedule), and any LECTURE NOTES. Once you submit your answers, your grade will be recorded in your Student Gradefile and you will not be able to retake the quiz.

Please complete this set of Study Questions before the end of the next class session. However, the absolute deadline for completing them is 10:00 p.m. Friday, February 27.
