Abstract
The burst signal of a color television signal is sampled at a rate which is a multiple of the burst signal frequency. A theoretical sample level of the burst signal is determined as a function of at least two of the actual sample levels thereof, the theoretical sample level representing a sample level that would be obtained if the burst signal is sampled at a predetermined phase angle. Based on the theoretical sample level and a predetermined one of the actual sample levels, a determination is made as to whether the burst signal actually is sampled at the predetermined phase angle. The phase of the sampling pulses which are used to sample the burst signal, is adjusted in accordance with the determination, such that the burst signal is sampled at the predetermined phase angle.
