trick Signal Scrunching

[Brian Crandall]

Overview

Chain View enables a nice visual of all the time periods stacked side-by-side; however, sometimes it is useful to create a new signal from all these capsules that has been scrunched together. Note this is different from "time warping" which realigns the samples by some amount.  Signal scrunching keeps the relative sample alignment the same within each capsule - but it does move each "snippet" of the signal next to each other.

Step

The best is to use Chain View and below method is applicable if there's a need to create a new signal.

This requires a Manual Condition with a single capsule so that we know the starting point where we will calculate delays from.

$delay = timesince($ManualCondition,1min,$Running)

$signal.within($running).move(-$delay,30days)
