This method, known as the rise time method, was theoretically justified for an impulsive source time function (Dirac delta function). . and .

The records from a three-component velocity seismometer at the depth of 145 m exhibit high S/N-ratio in a wide frequency range up to 100 Hz. Extended coda normalization methods were applied to bandpass-filtered
