Description
с сигналом сопровождени строки происходит формирование сигнала ошибки.An error signal is generated with the string tracking signal.
При записи информации на магнитный носитель по четному каналу могут быть записаны импульсы, представл ющие собой кодовую последовательность 1100, тогда по нечетному каналу записываетс последовательность ООН, т. е. обратный код.When recording information on magnetic media on an even channel, pulses representing the code sequence 1100 can be recorded, then the UN sequence, i.e. the reverse code, is recorded on the odd channel.
При воспроизведении же составл ют па ры из четных и нечетных импульсов ииформации и суммируют их по выбранному модулю . В частном случае модуль может иметь значение 2.When playing back, they make pairs of even and odd pulses and information and sum them over the selected module. In the particular case of the module can be set to 2.
При правильном воспроизведении информации сигнал ошибки не возникает, так как стробирование осуществл етс в момент нулевого значени полученной суммы импульсов . В случае же возникновени ошибки , котора может предстать в виде ложного импульса, сигнал ошибки будет формироватьс в момент стробировани единичного значени суммы сигналом сопровождающей строки. Если же ошибка будет заключатьс в том, что пропал один из импульсов информации, то и тогда она будетIf the information is correctly reproduced, the error signal does not occur, since the gating is performed at the moment of zero value of the received sum of pulses. In the event of an error, which may appear as a false pulse, the error signal will be generated at the time of the single-value gating by the signal of the accompanying line. If the error is that one of the pulses of information has disappeared, then it will
обнаружена в момент стробировани единичного значени суммы сигналом сопровождающей строки.found at the time of gating a single value of the sum by the signal of the accompanying line.
