    Can I oversample multiple identical digitized impulses to create a composite? How?

    I like that idea! I might have to give it a try. One thing I do need to do is re-learn Vbulletin. I screwed up and hit "post new thread" instead of reply. There's another thread that continues the saga here --> https://www.edaboard.com/threads/247074/#post1057565 The nutshell is that I was able...

    Low-tech method of solving the problem

    Argh, I must've hit the wrong button; i.e. "post new thread" versus "reply". So sorry about that!! Anyway, I would LOVE to improve the timing of the data at the time of creation, but what I am working with is a large data set of several million seismic files that were created over the course of...

    Low-tech method of solving the problem

    I've been looking at the problem this morning, and finally hit upon a low-tech method of solving the real problem, which isn't the creation of the impulse, but is in the calculation of the true sample rate. Since the sample rate varies by a slight amount, the pulses move back & forth depending...

    Can I oversample multiple identical digitized impulses to create a composite? How?

    I have a bit of a problem in that I have some digitally sampled seismic data with an unknown sample rate. It's close to 50 s/second, but not quite. Therefore when concatenating large sets of time-history data, the errors stack up until we see a missed sample, or even two samples that fall on the...
