Note: Values given bellow are typical values given as a rough guide. Depending on the required parameters
(B, T,…) other limitations may rise, e.g. side lobe levels highly depends on bandwidth (B) and time dispersion
(T), τ-3dB highly depends on bandwidth (B), …
The following parameter apply to each of the 2 channels (A and B)
