Abstract
Circuit device for automatic selection of reception conditions for color television signals according to PAL or SECAM systems, in which the chrominance signal after being separated from the luminance signal, is applied to a matrix unit of color through a PAL or SECAM demodulator, under the control of a discriminator-switch unit, characterized in that: the chrominance signal received from said bandpass filter (6) is applied to a detector unit (9) that includes a filter (14) tuned to a frequency that corresponds to a SECAM color carrier signal present in each second horizontal line and the output signal of said filter (14) is applied to a tuning circuit (17) tuned on half the line frequency and is then transformed into a direct current signal that operates a switch (8) to select the PAL or SECAM demodulator, so that a SECAM chrominance signal is supplied to the color matrix unit if the SECAM color carrier is present, while a PAL chrominance signal is supplied to the color matrix unit, if the PAL chrominance signal is present.
