BS 4478 is an international standard used for Measurement of intermodulation products in electronic tubes or valves intended for use in colour television transposers. This helps in manufacturing good quality intermodulation products in electronic tubes used in colour television transposers.
BS 4478 specifies the methods to be used for the measurement of the intermodulation
products which may be generated within any electronic tube or valve used in colour television transposers irrespective of the type or construction of the tube or valve.
BS 4478 on Intermodulation products in electronic tubes used in colour television transposers is useful for:
An electronic tube is useful in controlling electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
BS 4478 specifies the theory, test method and test procedure for electronic tubes. This test method is useful in measuring the intermodulation products. With the help of BS 4478, you can take precautions while manufacturing as well as installing these electronic tubes used in colour television transposers.
By applying BS 4478, you can improve the image quality of these colour television. This results in manufacturing good quality intermodulation products in electronic tubes used in colour television transposers.
