Analysis of digital data two


Digital Data Analysis is part of De Montfort University FdSc in forensic collision investigation.

This module expands on the learning in Digital Data One where we looked at wheel speed and GPS data.  

What you will study

The module is new for the 2023 academic year.  It picks up where Digital Data One left off and is primarily concerned with accelerometer data. Accelerometers are everywhere but in relation to collision investigation we are particularly interested in insurance back boxes, emergency brake testers and event data recorders (EDR's). 

If we are going to use this data as part of the reconstruction process we first need to understand the data and know how to process it.  This module looks at,        

  • Accelerometer fundamentals - What are they and how do they work

  • Sampling and signal processing - Types of sampling, sensitivity and sampling rate

  • Accelerometers in the real world - Frames of reference and number of accelerometers

  • Bias Drift and Error - The effect of horizontal misalignment, rotation and tilt

  • Numerical Methods - Differentiation and Integration, errors, stability and convergence
