  Scientific CCDs designed in thick high resistivity silicon (Si) are excellent
detectors for astronomy, high energy and nuclear physics, and instrumentation.
Many applications can benefit from CCDs ultra low noise readout systems. The
present work shows how sub electron noise CCD images can be achieved using
digital signal processing techniques. These techniques allow readout bandwidths
of up to 10 K pixels per second and keep the full CCD spatial resolution and
signal dynamic range.
