    Two RF conducted noise measurement systems have been developed for laboratory measurements of automotive electrical and electronic devices. One is a noise emission measurement system for measuring noise level from the electrical devices while the other is a susceptibility measurement system for measuring the susceptibility level of the electronic devices to the noise. The former's function is to m... View full abstract»

    Speech security communication systems applied to radio analog speech channels become more and more desirable as radio channel capacity increases and service area spreads. Analog spectrum inversion used in existing radio communication systems is suitable for preventing eavesdropping and ensuring security, but it suffers from inevitable speech quality degradations. It is shown that digital spectrum ... View full abstract»

    Two methods of speech detection at the syllabic level of voice traffic over land mobile radio telephone channels are presented. Both methods are based on the periodic comparison of the audio signal level with a threshold and provide an ON-OFF pattern of active-idle periods on the channel at a rate equal to 100 to 200 samples per second. One method is entirely digital whereas the other method uses ... View full abstract»

    An asymptotic analysis is performed to obtain the E- and H-fields in the close vicinity of dipole and helical antennas. Although the mathematical procedure requires some involved algebra, the resulting series representation of the fields lends itself to simple numerical calculations. It is shown that the asymptotic E- and H-field values are in very good agreement with both the experimental results... View full abstract»
