Application
The Recommendation applies to homogeneous analogue or mixed
analogue-and-digital
The requirements below apply to the hypothetical reference circuit (HRC) defined in Recommendation J.11.
For estimation of the performance of circuits shorter or longer than the HRC, see CCIR Recommendation 605.
Note 1 - For all-digital circuits a separate Recommendation might be envisaged after further study.
Note 2 - For further work, CCIR Report 496 may be consulted. This Report also draws attention to certain differences between CCIR and OIRT Recommendations.
