Timefrequency representation of a linear chirp signal

1
Time-frequency representation of a linear chirp
signal
Comparison of time-frequency localization for a
benchmark system (wavelet packets with a 30-tap
Coiflet system) and for my framelet-based system
with respect to a uniform sub-band decomposition
of a linear chirp signal.

Time-frequency representation of a musical
instrument signal
Time-frequency representation of a vibraphone
recording using my framelet-based algorithm. The
sub-band signals are represented at the original
scale (via reconstruction), and have been
combined from a narrow-band representation to
approximate a region of the log12 musical scale.
