Figure 1. The Meyer wavelet (upper plot) at scale 14 (center period, 1 sec) and its
frequency-domain representation (middle plot) normalized to the maximum value.
The frequency response of a zero-phase (three poles, two passes) Butterworth
filter between 0.4 and 1.3 Hz (dotted line) and between 0.55 and 2 Hz
(continuous line) is presented in the bottom plot. The sample rate is 20
samples/sec.
