    2.1 Block diagram Figure 1. CSR-DMT block diagram Presence of various nodes can be different for different ordering options of CSR-DMT. 2.2 Filters characteristics In this section digital filter characteristics are described. Digital filter node is purely software based, thanks to that it is possible to reconfigure selective filters in a desired way without any change to the hardware.
  • Page 7 If needed the repeater pass band can be constructed from two or more segments. For instance using such a composite method with filters from group 1 (see table above) it is possible to make wideband filter with best selectivity properties. Applying composite method it must be taken into account the real transition band in amplitude-frequency response of the filter.

    Channel attenuation can be adjusted manually for each channel (figure 8, 6 uplink) and also for all four channels of up (figure 8, 7 uplink) and down links jointly with physical attenuators (see figure 1 “CSR-DMT block diagram” for details). Resulting gain for each channel is displayed in the “Total Gain” boxes for up and down links.
