MIXER ACTION AND ITS INFLUENCE ON INTERFERENCE AND FREQUENCY ASSIGNMENTS
Abstract
From a review of the action of the mixer under some simplifying assumptions, it is shown that, in problems of interference likely to be encountered in practice, the power of the spurious interference products can be simply expressed in terms of the undesired and of the local oscillator voltage inputs to the mixer. The construction and some of the characteristis of the mutual interference chart are briefly reviewed. An expression giving the importance of any interference product relative to the signal is developed. By the use of propagation law, this relation is expressed in terms of the field parameters. the resulting relation is useful in estimating relative importance of products or lines as a function of the distance separating desired and undesired transmitters. The role of these relations and the chart in developing systems of frequency assignments is briefly outlined. (Author)
