In the field of DSP engineering we like keeping the expression "1/z"
in the form of "z minus one", namly in a exponential form. Both the "z
minus one" and "1/z" has the same "FullForm", namely "Power[z,-1]".
But they both get displayed in a fractional form. how could I change
that way of diplaying "Power[z,-1]"?
