# time-series-filter

Some convenient traits and types for
processing sequential data.

- `FloatSeriesEwmaFilter` can be used to track the 
exponential weighted moving average (EWMA) of a varying
signal.  This is essentially an infinite impulse response (IIR)
filter and a low pass filter (LPF).
- `IntSeriesEwmaFilter` creates a filter for integer types, 
which avoids floating point math.
