Method and device, 1984, error correction phase during the sampling of a sine wave signal by a clock signal, as well as the application to the correction of television signals.

摘要

During the conversion of analog -, 1984, by sampling of a sine wave signal of frequency f by a clock signal of frequency 4 nf, n being an integer, these two signals present a residual phase error. / p & & p & the method of correction of the signal, 1984, converted according to the invention comprises a delay that - treatment of n periods of the clock signal in a register a spacing difference 10, to multiply, 13, the signal is not delayed by cosph and multiply 14, the signal delayed by sinph and to transmit the results in an adder 15. / p & & p & the process applies in particular for the correction of the chrominance signal of the television type or of composite n.t.s.c. p.a.l.
