Supervisor:

Department of Radioelectronics

Synopsis:

The course is devoted to a detailed system and theoretical analysis of TV systems and includes a description of procedures required for the image-to-signal conversion. Further the TV signal processing analysis is mentioned with respect to the losses of image information in presence of noise. This is a preparatory course for MSc. students interested in TV production and videotechnology.
