Deconvolution of causal pulse and transient data

When deconvolution processing is applied to remove instrumentation errors and/or suppress the effects of noise, noncausal deconvolution methods may introduce unacceptable errors. The Nahman-Guillaume (see NBS Tech. Note 1047, Oct. 1981) automatic deconvolution method is modified to ensure that causality is maintained in the deconvolution result. The method may be applied to other deconvolution methods. Simulated and experimental examples using the Nahman-Guillaume method which show the undesirable effects of noncasual methods and a means to eliminate such effects are given.<
