Reconstruction of an Analytic Signal.
L.P. Mulcahy · Defense Technical Information Center (DTIC) · 1967
Computation of envelope and frequency of an analytic signal based on sampled data has been shown to be feasible. However, there exist a number of problem areas that need investigation before we can specify the amount of accuracy that these computations yield. These areas constitute a list of possible sources of error: the error due to the use of non-band limited signals; the error caused by the equivalent noise associated with data acquisition devices; the approximation error due to the use of finite data samples in reconstruction; and computation error in the digital computer.
