PROCESSOR OF MULTI-TRACKING SIGNAL IN MONO VCR

摘要

PURPOSE: A processor of multi-tracking signal in a mono VCR is provided to selectively listen a multi-tracking broadcasting of the mono VCR. CONSTITUTION: By selecting a foreign language to listen a broadcasting in the foreign language, a control unit(20) switches to a processing module of multi-tracking signal(22) to selectively output a multi-tracking signal by controlling a switching unit(23). An SIF signal outputted from a tuner(21) is outputted to an FM detecting unit(22b) after filtering a second sound carrier frequency(a frequency of foreign sound signal) of 4.72MHz in a filtering unit(22a). The user is able to listen the TV in the foreign language. When a selecting key of Korean is fed to the control unit(20) to listen the TV with the Korean as a first sound signal during listening with the second sound signal, the control unit disconnects a switching point of the switching unit(23) to an a terminal.
