The latvian academy of culture

The Name of the Course: Television Technology. Electrophysics for TV Cameramen, The Fundamentals of Television, Television Apparatus, their Exploitation.

The Scope of the Course: 112 hours (102 lectures, 10 hours of seminars). 4 terms. 7 credit points. Type of Assessment: an oral examination.

X.The Author of the Course: Lecturer Aivars Ragovskis

The Content of the Course: The course is a preparatory stage for the disciplines of the following terms: “The Fundamentals of Electronics”, “TV Technologies”, “TV Signal” and “Digital Technologies”.
Preconditions for the Acquisition of the Course: The knowledge of physics at the level of secondary school is required. To work with video equipment it is necessary to be familiar with the structure of the electronic camera, its operational principles and its flow charts. Its simplest defects should be diagnosed and eliminated.
