ocr: 0.9 0.8 07H - 0.6 0.5 04H - 0.31 50 100 150 200 250 Figure 5: Low-Pass Filtering by JMA: A time-series (red, jagged) is filtered by JMA (blue, smooth), with smoothness set to 15 and phase set to 100 minimum lag, maximum overshoot). Note that while JMA does track the signal well, it does lag the hardest reversals (notice, for example, the 3 largest downward spikes in the signal). This will produce some unwanted artifacts in derived high-pass and high-boost filters.
