发明名称 Arrangement for converting special channels of television into television channels of the UHF band
摘要 The invention relates to an arrangement for broadband conversion of the special channels of television into channels of the UHF band. For this purpose, the two special-frequency bands of the special channels of television are separated from one another and subjected to separate mixing at the same mixing frequency. At the output of the two mixers, the converted UHF frequency bands which in each case result as upper side band of the sum of mixing frequency and special frequency band can be filtered out via band-pass filters and supplied to a common output without any interfering influence occurring due to the other interfering mixing products of any order occurring.
