Description
StrangNguyenProblemSetEducationalExample1
This DrawingBoard provides the solution to Problem Number 3 in Problem Set 3.4. p 102 of the text "Wavelets and Filter
Banks" by Gilbert Strang and Truong Nguyen, Wellesley-Cambridge Press, 1996.
It involves determining the output sequences from a cascade of down- and up- samplers (as presented in the
DrawingBoard), for a chosen input sequence (selected using the 3-way switch).
Select an input sequence from the ASCII files "impulse.txt", "ones.txt", and "telegraph.txt" (in the ascii/audio subdirectory
of the WaveWarp root directory) which contain identically the sequences posed in the Problem Set i.e. (1,0,0,0,...),
(1,1,1,1,1,....) and (1,-1,1,-1,1,-1....) , respectively. Select an input, and play the DrawingBoard. Inspect the
output ASCII file "NewMono.txt" (in the ascii/audio subdirectory of the WaveWarp root directory) with a text editor (e.g.
Notepad) to see the output for the chosen input sequence.
