Study Questions #7: FM synthesis

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.

1. One of the greatest advantages of FM synthesis is its ability to create complex wave forms (rich sounds) with a minimum amount of computation.
2. Frequency Modulation techniques are a relatively recent invention and have only been used in the field of sound synthesis.
3. One of the people most responsible for developing FM techniques for synthesizing sound was:
4. In FM synthesis, the most basic components are:
5. When the MODULATING FREQUENCY is above 20 Hz, then additional frequencies are created which are arranged symmetrically around the CARRIER FREQUENCY. What are these "additional frequencies" called?
6. If the SIDEBAND frequencies result in a negative value (for example, -50Hz) then they actually appear with a PHASE SHIFT of how many degrees?
7. If the MODULATING FREQUENCY is below 20 Hz, then the modulation is perceived as:
8. The ratio of the modulation amount in the modulator's amplitude field to the frequency of the carrier is called the:
9. The STRENGTH of the modulation depends on the:
10. For many sounds, the most complex part of their spectrum is during which aspect of their envelope:
