Abstract

Circuit arrangement for generating a clock signal which is rigidly locked to the line frequency, for decoding digitised television signals. The clock frequency is generated with the aid of a first PLL circuit which receives as reference frequency the reference frequency generated with the aid of a second PLL circuit, which is locked to the line frequency.
