Methods for transposing elements of a sequence according to a rule, wherein the rule is derived from pseudo-noise or pseudo-noise like binary and non-binary sequences are disclosed. The frequency error is detected by the average speed of rotation of the I,Q constellation. The RRAM cell structure also includes a resistance variable layer over the first electrode. After a predetermined time period has passed, the inner wheel and the outer wheel are separated from each other and independently rotated at different speeds before stopping. An available tape drive is then selected to mount the physical volume, and an entry in the tape drive table is updated to claim ownership of the tape drive. Since diagnostic analog parameter values require differing sampling rates to be effectively measured, the schedule for converting those values to digital value should correspond to the associated sampling rate.
