ENSURING ELECTROMAGNETIC COMPATIBILITY WHEN PLANNING FREQUENCY-AREA CTV
The basic principles of 3 computer programs for ensuring EMC are given below.
Program KANAL-TV is used for optimum selection of distribution TV-channels in CTV which ensure interference quantity minimum of intermodulation, harmonic, adjacent and image channels in TV-receiver.
These types of interference are made by other distributed signals in CTV and TV-heterodyne.
Program ASTRA-TV is used for calculation of minimum of frequency-area diversity between CTV head station and other transmitters (cellular, paging, tranking, FM sound)operating in bands 30-48, 57-57,5 and 150-174 MHz.
Program CHASTAN is used for calculating the high order intermodulation interference which are formed at the CTV input because of unwanted signals from other transmitters.
