Abstract: A method and system for processing finite frequency domain data to which a time gating process is to be applied to improve performance of signal processing equipment and to facilitate complex time gating while suppressing edge effects. According to one aspect, a method for improved processing of a finite frequency signal by signal processing equipment to suppress edge effects arising from a time gating process is provided. The method includes padding the finite frequency signal outside a frequency range with samples derived from an extrapolation process to produce an extended signal having samples inside and outside the frequency range of the finite signal. The method further includes applying a time gating process to the extended signal to exclude signals occurring outside a time interval and to produce a time gated signal with suppressed edge effects.
