1. A method for processing a scalogram, the method comprising: receiving a signal from a signal generator; using processing equipment for: generating the scalogram based at least in part on a continuous wavelet transform of the signal, sampling the signal, convolving the samples of the signal with wavelet coefficients to produce skewed scalogram samples, deskewing the skewed scalogram samples to produce scalogram update samples, updating the scalogram by adding the scalogram update samples to the scalogram, and determining information from the signal based at least in part on the updated scalogram; and outputting the information to an output device.
