Module name: MovingRMS

Package: CEAMSModules 7.4.0

Version: 2.0.0

Overview

Compute RMS (Root Mean Squared) value on a moving window.

Inputs

Input

Format

Default

Description

signals

a list of SignalModel

—
signal.samples : The actual signal data as numpy list
signal.sample_rate : the original sampling rate of the signal
signal.channel : current channel label

win_len_sec

float

1

window length in sec (how much data is taken for each RMS computation)

win_step_sec

float

1

window step in sec (each time the RMS computation is applied)

Outputs

Description

moving_RMS_values

dict of SignalModel object, the key is the label of the channel.

moving_RMS_values[channel_label].samples: One RMS value per moving window as numpy array.

Usage in a process

  1. Open Dev Tools -> New process in Snooz.

  2. In the Module Library, find Moving RMS under the Signal Processing category.

  3. Drag the module onto the process canvas.

  4. Connect the required inputs from upstream modules (or set values in the Settings tab).

  5. Connect outputs to downstream modules as needed.

  6. Double-click the module to configure parameters in the Settings tab.

  7. Run the process and inspect results in the Results tab.
