Sampling System And Its Effect On The Speed Of System

1 . INTRODUCTION There are plenty of sampling systems are present. By using those kind of sampling system it may causes large amount of distortion. Distortion includes aliasing, jitter, noise, aperture error etc. Aliasing. Some amount of aliasing is inevitable because only theoretical, infinitely long, functions can have no frequency content above the Nyquist frequency . Aperture error results from the fact that the sample is obtained as a time average within a sampling region, rather than just being equal to the signal value at the sampling instant. Jitter or deviation from the precise sample timing intervals. Noise, including thermal sensor noise, analog circuit noise, etc. In order to reduce the jitter and increase the speed of system we use wide band photonic compressive system. It mainly used for the periodic nonuniform sampling of signals. Topic relevance and applications Wideband photonic compressive sampling system consist of many advantage over the other sampling system.Sampling is the reduction of continuous signal to a discrete signal. A common example is the conversion of a sound wave to a sequence of samples Wideband photonic compressive sampling system is a type of sampling system mainly used for periodic nonuniform sampling. Sampling is the reduction of continuous signal to a discrete signal. A common example is the
