摘要

A method of determining the mode of a digital signal is received and a VSB receiver to receive digital VSB signals that include informaciondel VSB Mode.The receiver includes a Detection Circuit of VSB mode with a characteristic filtrode Comb potential lack of Synchronism Solves the problem in a situation where a Signal mode8 VSB is being received, being active in ysubitamente Comb Filter characteristic is odalidad Lam produces a change in Signal.The available Inhibits the first two bytes of the information so cuyosdos Three bytes, bytes are inespecificados for All Modes except 8 VSB Terrestrial Mode.And replaced by Zero Data. In otrareal ization, the delay of 12 symbols in the Comb Filter characteristic is derived with the complement of the input data for the Third byte.When it is determined that there is a reliable Way of 8 VSB Terrestrial Mode.Lainhibicion First byte (byte and the second and the Third Investment bytederivado) is eliminated in Alternating fields to allow normal operation of the Comb Filter characteristic at.
