Abstract
In odd‐depth structure the two‐way traveltime to each boundary is constrained to be an odd integer. The odd‐depth property of a model is exposed to possible refutation under a seismogram test. Test function is a simple transformation of a synthetic seismogram. For an odd‐depth model the test function has identically the value 1.
The testability of a synthetic seismogram over an odd‐depth structure provides a method of deterministic deconvolution. There is no need of specialized assumptions, like the minimum‐phase property, about the source wavelet. The deconvolution may be performed in the absence of the early segment of a seismogram.
