Signal processing

Raw measurements often contain noise, interference and overlapping effects. MNC Analytics develops signal processing methods that isolate relevant information and support reliable detection, diagnosis and estimation.

We work with vibration, acoustics, electrical measurements, images and other time-dependent data. Our methods connect the characteristics of the signal with the physical behaviour or operational event being investigated.

  4. 04

    Fault signatures, diagnostic models and operating-state classification

  5. 05

    State estimation, localisation and tracking

  6. 06

    Multisensor analysis and uncertainty-aware interpretation

  7. 07

    Evaluation of detection delay, missed events and false alarms

What this enables

More informative condition indicators, clearer diagnostic evidence and analytical inputs that reflect the behaviour of the underlying system. Solutions can be deployed within research tools, monitoring platforms or embedded devices.
