The seismic source signature s is a causal wavelet. Signature deconvolution is the process of removing the signature wavelet from the seismic trace by means of the inverse of the signature. When the signature is not minimum phase, the inverse of the signature is a noncausal (two-sided) filter. The input to the signature deconvolution filter is the field trace; the desired output is the signature-free trace.
