A device for recovery of clinical in the large capacity memoires

摘要

P the invention relates to a device for recovery of digital data in order to extract the coded data in memories of large capacity. / p & & p & the device comprises a clock generator of a window which is connected to a synchronizer of data and to a control circuit of the clock which generates signals of the reference clock, a counter of columns, which is connected to the clock generator of the window, makes it possible to a counter pilot to establish the mean number of clock signals between the reference data bits ra, for a variable number of columns of data, and a decoder / phase-locked circuit connected to the counter is possible to reset the clock generator of the window, by means of a selector outputs of the window, each time a data bit has been read, a window generator, connected to the counter of columns, makes it possible to a detector of the data and of error, with the synchronizer, to generate the sampling signals, data and error at the output. The application: reading tracks multiple magnetic memories. / p
