Digital Filter Structures and Quantization Error Analysis
Practical implementations of digital filters introduce errors due to finite-precision data and arithmetic. Many different structures, both for FIR and IIR filters, offer different trade-offs between computational complexity, memory use, precision, and error. Approximating the errors as additive noise provides fairly accurate estimates of the resulting quantization noise levels, which can be used both to predict the performance of a chosen implementation and to determine the precision needed to m

Japanese tea ceremony: A critique for screens and scrolls
The last part of a larger unit on discussing and evaluating Japanese screen and scroll paintings as well as creating one. The purpose of this unit plan is to introduce descriptive aspects of art criticism while teaching them the art and culture of Japan.
Students will understand the life cycle of the butterfly and create various art activities that would model metamorphosis.
The scarlet "A": Role-play in writing
This lesson was created to follow a close reading and examination of Nathanial Hawthorne's "A Scarlet Letter". The plan uses a small group format and rotation schedule. The activities created strengthen students' understanding of an author's use of characterization, while reinforcing reading and creative writing skills.
Awesome Action Words
Good writers use precise verbs to make stories interesting and vivid. In this lesson, students will learn to replace boring, redundant, generic verbs with more precise "Awesome Action Words."
