SMOOTH THE CURVE¶
Applies iterative moving-average smoothing to a curve using forward, backward, or combined forward-backward passes over a configurable window of points. Use this worker to reduce noise in time-history or signal curves before downstream processing or KPI extraction.
When to use¶
Classification: process.
Tagged: curve, forward_backward, iterative, moving_average, noise_reduction, signal, smooth, time_history.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve In | curve_in | vector | — | Input curve (x/y vector) to be smoothed; accepts any time-history or signal curve in the platform’s standard vector format. | |
| Smooth Type | smoothtype | string | forward_backward | Direction of the moving-average pass: ‘forward_backward’ (default, symmetric, recommended for most signals), ‘forward’ (causal, left-to-right only), or ‘backward’ (right-to-left only). | |
| Num Points | num_points | integer | 4 | Window size (integer, default 4) — number of consecutive points over which the local average is computed; larger values produce heavier smoothing. | |
| Iterations | iterations | scalar | 1 | Number of times the smoothing pass is repeated (default 1; options up to 100); higher iteration counts progressively flatten the curve — increase when a single pass leaves residual noise. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_smooth_iterative_output_1 | curve_smooth_iterative_output_1 | vector | Smoothed output curve (x/y vector) with the same domain as the input but with high-frequency noise attenuated according to the chosen smoothing type, window size, and iteration count. |
