Definitions

  • Fig. 5 shows the connection between the attenuation and the frequency for each of the partitions 7 and 8 (curves 15 and 16) and for the combination of the two partitions (curve 15 + 16)in the pass range of the band of 11.35 - 11.8 GHz. In this band the attenuation is only very little larger than for each separate partition.

  • Control And Other Processes For Unpacking Of Materials (AREA)
  • Inductance-Capacitance Distribution Constants And Capacitance-Resistance Oscillators (AREA)
