#23 Question: Construction almost tight frames

I want to construct a tight frame or a frame where the upper and lower
bound are not far apart. I would prefer the frame to have an analytic
expression in the time domain. I only want one scale however. Any help
in doing this would be greatly appreciated. Also information on
computing frame bounds would be helpful. Specifically, compuations
such as the following: the Harr basis forms a tight frame when they
are orthogonal and when they are used in a continuous wavelet
transform, what happens for the case where the Haar functions are more
redundant than the orthogonal case, how does one compute frame bounds
for different redundancies ?
