A function block of a radio receiver which is well characterized by
Y1(t+d1) = k _{11}X1(t)+ k_{12}{X1(t)}^{2}
+ k_{13}{X1(t)}^{3} + … ......... (1)
is connected in series with another function block which is
well characterized by:
Let us find out what Y2 becomes when expressed in powers of X1
by putting:
Y2(t+d1+d2) = k
We pick all terms up to third order:
It is obvious that two series connected units that are both well described by a polynomial expansion will also be described by a new polynomial expansion. |
