Sampling conversion of the short impulse signals at extended sample width

The paper presents results of study of sampling conversion when the sample width is comparable to duration of the impulse which to be registered (in other words impulse spectral width is wider than the receiver bandwidth) but sampling step is much less then sample width. The conversion features of the pulses with Gaussian shape and its first derivative at different sample width are considered in present work. The effect of the analog accumulation and its influence on the converted signals shape also has been studied.
