Design Objective
  • Any desired performance characteristic for communication circuits and equipment which is based on engineering judgment but, for a number of reasons, is not considered feasible to establish as a system standard at the time the standard is written. Note: Examples of reasons for designating a performance characteristic as a DO rather than as a standard are: a. it may be bordering on an advancement in the state of the art; b. the requirement may not have been fully confirmed by measurement or experience with operating circuits; c. it may not have been demonstrated that it can be met considering other constraints such as cost and size. A DO must be considered as guidance for DoD agencies in preparation of specifications for development or procurement of new equipment or systems and must be used if technically and economically practicable at the time such specifications are written. See also specification, standard.
