A method of and system for signal analysis includes acquiring multiple signals from the environment by using multiple sensor elements, applying a transform which combines the multiple acquired signals into a single combined signal, and reduces the number of samples in the combined signal, applying a single signal analysis and event detection operation on the resultant combined, sparse signal, and performing a complete signal analysis using multiple analysis elements for the multiple input signals only in the case where the sparse signal analysis indicates that the event of interest may be present. |
