Cable compensator circuit for CCD video probe

摘要

Picture noise in a CCD video probe is reduced by producing a faithful reproduction of a reset-gate signal received from a timing generator to an imager by using a cable compensator network. The network contains an RLC circuit which corrects the relative amplitude and phase of the various frequency components of the reset-gate signal. The precise values of the components in the RLC circuit are selected according to the attenuation and distortion characteristics of the coaxial cable connecting the drive electronics assembly from the imager assembly.
