Direct Graphical Determination of Optimum Shielding and Suppression

Signal parameters which will result in satisfactory levels of interference can be obtained directly from the graphs included in this paper. These graphs may be used to determine permissible waveforms for pulses, step functions, and CW signals for compliance with broad-band radiated, narrow-band radiated, and conducted interference limits. Curves are included for MIL-I-26600, MIL-I-6181D, MIL-I-11748, and MIL-STD-826. The curves are extremely simple for designers to use in determining shielding and suppression requirements. They may also be incorporated into the interference control plan to indicate to the customer that adequate interference control techniques will be incorporated.
