When the value of [C.sub.j] of the varactor is in the range [C.sub.sc] [less than or equal to] [C.sub.j] [less than or equal to] [C.sub.oc], then, the input reactance [X.sub.n] of the varactor terminated line
can take any value from that of a short circuit to that of an open circuit (i.e., 0 [less than or equal to] [X.sub.n] < [infinity]).
There was the sudden crack of phone on cradle, then the purr of a terminated line
We first discuss the propagation loss [L.sub.db] in a perfectly terminated line. If R, L, G and C are the primary constants of a line and [omega] = 2[pi]f, where f is the frequency, then
For a perfectly terminated line with the length /, the transfer function H (l, f) of metallic homogeneous symmetric lines is given by
One possible explanation is impedance mismatches in a source series terminated line
. If the source series resistor was too high, it might cause this effect.
