For an FIR filter, with symmetrical tap values h[N−1−n]=h[n],
- why is the group delay N−12T (where N is the number of taps of the FIR filter and T is the sampling time)?
- Why is linear phase so important for the filter response?
Apparently the of last four, MgX2+ is closest in radius to LiX+. Is this true, and if so, why would a whole larger shell ($\ce{...
