The Haar Wavelet Filter Bank
In this Haar Wavelet learning exercise, students solve and complete 4 different problems related to the Haar Wavelet filter bank. First, they define the properties of Haar basis. Then, students compute the matrices for the first, second...
Curated OER
Worksheet 21
In this math worksheet, students draw two vectors u and v based at the same point. The vectors are considered neither parallel nor orthogonal.
Curated OER
Worksheet 23 Spring 1996
In this math worksheet, learners fill in the missing boxes while investigating the concept of vectors. They determine if two vectors are orthogonal or parallel.
