Abstract
A decoder circuit arrangement for a multi-system television receiver for treating at least one amplitude demodulated signal and one frequency modulated signal, including a switchable chrominance signal path splitter in a modulation signal path. amplitude and a frequency modulation signal path, in which the frequency modulation signal path includes a limiter, characterized in that the signal path splitter includes a first transistor (1) coupled to an input thereof and that its emitter is connected to the emitter of a second transistor (5) and, through a first resistance (9), to a first current source (11), whose connection between the first resistance (9) and the first source (11) is also connected, through a second resistance (15), to the emitter of a third transistor (17), each of the bases of the second and third transistors (5, 17) being connected to n input (7, 19) different from the system switching voltage, at least one of the collectors of the first and second transistors (1, 5) being connected to a frequency modulation output of the signal path separator, and being At least one of the collectors of the first and third transistors (1, 17) connected to an amplitude modulation output of the signal path separator.
