Abstract

See full text

An engine analyzer includes an A/D converter for sampling analog data from an engine under test and developing digital data consisting of 11 magnitude bits and a sign bit. Four flag bits are added to make a digital word of sixteen bits with the four added bits being equal to the sign bit. Flags are set by making their bit value opposite to that of the sign bit. The sixteen bit words are stored in a RAM memory and the presence of the flags enables ready identification and retrieval of the data.
