STARMS

Purpose:

Calculates the short time averaged RMS series.

STARMS(series, intv)

series	-	An input series
intv	-	Optional. An integer, the duration of each RMS segment. Defaults to 1.0 second.

A series, the short time averaged RMS series.

W1: gsin(1000, .01, 1)

W2: starms(W1)

W2 consists of a 10 point series where each point has a value of 0.707107, the RMS value of each 1 second segment of W1.

W4: starms(W1, 0.1)

W4 consists of a 10 point series where the values now vary since the RMS value of W1 varies over a 0.1 second interval.

The number of segments used to calculate the RMS value is

segsize = int(interval / deltax(s))

where s is the input series.

The segments are non-overlapping.
