A Signal Processing Expert Witness may compare the source data, sampling rates, processing steps, filter parameters, transform settings, software methods, windowing choices, and other analytical assumptions used in each analysis. Reproducing or comparing those steps can help determine whether the differing results arise from characteristics of the underlying signal or from differences in how the data was processed.
A digital recording represents measurements taken at specific sampling intervals. If the sampling process does not adequately capture the frequencies present in the original signal, higher-frequency content can appear incorrectly as lower-frequency content. A Signal Processing Expert Witness may review the sampling configuration, expected signal bandwidth, filtering, acquisition settings, and source records to assess whether aliasing could have affected the resulting data.
Filtering can suppress or emphasize selected portions of a signal, while spectral analysis can reveal frequency components that may not be apparent from the waveform alone. A Signal Processing Expert Witness may examine filter characteristics, processing settings, spectra, and original data to determine whether a reported feature was present in the source signal or was materially affected by the analytical method.
Signal Processing expertise focuses on the mathematical and computational analysis of signals, including sampling, filtering, transforms, detection, modulation, and interpretation in the time or frequency domain. Radio frequency engineering more broadly addresses RF generation and transmission, antennas, propagation, circuits, interference, and wireless-system behavior. When the central issue involves propagation, antenna performance, or RF hardware rather than analysis of the signal itself, a wireless or electrical engineering expert witness may provide more specialized analysis.
Prepares clear, well-supported expert reports outlining methodology, analysis, findings, and opinions.
Provide Deposition Testimony
Explains findings and opinions under oath and responds to questioning during deposition testimony.
Testify in Court
Presents specialized findings and opinions clearly to judges, juries, arbitrators, or other decision-makers.
Signal Processing expertise may become relevant when a communications dispute centers on waveform characteristics, modulation, signal detection, noise, filtering, interference effects, or extraction of information from a communications signal. When the primary issue instead involves routing, switching, addressing, packet traffic, protocols, or network configuration, a computer networks expert witness may provide more specialized analysis.
