  • However, when the bursts are sparse, so that the largest amplitude bursts are mostly nonoverlapping, then very precise estimates of the single burst frequency can be made using a relatively high amplitude threshold to eliminate all the lower amplitude signals which contain a high degree of perturbation of the instantaneous frequency due to multisignal interference.
