frequency band造句
61, ADSL uses the high frequency band which has not been used in the common telephone line and the advanced modulating technique to provide broadband access. 62, Simulation results show that efficiency and can operate over the whole main - mode frequency band. 63, Then the every frequency amplitude of auditory correlogram was coded as a feature vector expressing present frequency band characteristic. 64, What's more, because the middle direct voltage is high up to 2800V, the sensors need higher insulated voltage and wider frequency band. 65, Turbulent characteristics of different frequency band in constant volume combustion bomb can be realized by changing the structure of the perforated plate and the velocity of driving motor. 66, Each antenna element either resonates independently or increases the total bandwidth of operation in the high frequency band. 67, ADSL is a branch of DSL technology, but also the use of ordinary telephone lines to transmit data, but it is used in high frequency band than the voice . 68, The spectral compressor compresses a pre-selected portion of the high frequency band and maps the compressed high frequency band to a lower band limited frequency range. 69, Our company has strong development capabilities, self-developed 30-point frequency band launch teaching reading, the current leader in China.
