FIELD: measuring technology. SUBSTANCE: method may be used for measurement and check of qualitative indicators of TV path and channel for sound transmission, including radio broadcasting channels. Realization of method is based on joint usage of device of analog-to-digital conversion of TV, radio broadcast and PC signals and program complex. Usage of method provides for fast measurement to obtain results in real time, for high measurement precision, for expansion of nomenclature of measured parameters and possibilities of further expansion of nomenclature by built-up of complex of programs, for graphically of presentation of measured parameters with capability of their indication on screen of display up to reconstruction of analog shape of measured signal by means of digital-to-analog conversion. Method demonstrates all these advantage thanks to implementation on personal computer of program realization of processes of control, measurement and check due to abandonment of analog processing of measured signal, due to its replacement with digital processing and usage of all advantages provided by digital computation equipment. EFFECT: provision for fast measurement of parameters and high precision of measurements. |
