Fig. 8From: Detection of low-frequency earthquakes by the matched filter technique using the product of mutual information and correlation coefficientMI, CC, and MICC for the test between the template waveform and synthetic data (random noise and template waveforms). MI, CC, and MICC are calculated every 0.04Â s (every sampling point). The template waveforms were added to the noise every 400Â s with various SN ratiosBack to article page
