Root trainer Root trainer A root pruning container is an aid to the cultivation of young plants and trees in nurseries. Many pot designs train the roots. One example is a truncated plastic cone in which a seedling is planted. There is a drainage hole at the bottom and the main tap root tends to grow towards this. What this achieves is to encourage the roots the grow a denser system of root hairs. How it does this is to have the pots designed so as to air prune the roots. The advantage is when the plant is planted into its home
Root-raised-cosine filter impulse response is not zero at the intervals of ±"T". However, the combined transmit and receive filters form a raised-cosine filter which does have zero at the intervals of ±"T". Only in the case of "β"=0 does the root raised-cosine have zeros at ±"T". Root-raised-cosine filter In signal processing, a root-raised-cosine filter (RRC), sometimes known as square-root-raised-cosine filter (SRRC), is frequently used as the transmit and receive filter in a digital communication system to perform matched filtering. This helps in minimizing intersymbol interference (ISI). The combined response of two such filters is that of the raised-cosine filter. It obtains its
