DM

Logical Entity Name	DM
Default Table Name	DM
Definition	Summary information on a decimation

DM Columns

ColumnName Domain Datatype NULL Definition

key (PK) NUMBER(8, 0) NO This attribute denotes a unique identifier for a decimation

name VARCHAR2(80) YES Descriptive name

samprate DOUBLE PRECISION NO Sampling rate. This attribute is the sample rate in samples/second

factor NUMBER(8, 0) NO The decimation factor. When this number of samples are read in, one final sample comes out. The output sample rate can be calculated by dividing samprate by the decimation factor

offset NUMBER(8, 0) YES This field determines which sample is chosen for use. The value of this field has to be greater than or equal to zero, but less than the decimation factor

delay DOUBLE PRECISION YES The estimated pure delay for the stage

correction DOUBLE PRECISION NO The time shift applied to the time tag due to delay at this stage of the filter; a negative number indicating the amount of time added to the former time tag. The actual delay is difficult to estimate, and the correction applied neglects dispersion.This field allows to know how much correction was used, in case a more accurate correction is to be applied later. A zero here implies no correction was done

lddate DATE YES Load date. Date and time that the record was created or last modified, in Oracle date datatype
