Abstract :
The SNR of TEMPEST leaking signal and bandwidth for receiving of receiver were key factors of affecting information recovery. To improve the quality of information recovery, make mention of the conception of prime bandwidth for receiving and present the definition of prime bandwidth for receiving. Relation between prime bandwidth for receiving and SNR of signal has been researched, as well as relation with characteristic of frequency domain of signal. Make digital baseband signal as an example for deducing prime bandwidth for receiving and discuss the prime bandwidth for receiving aiming at complicated signals.
