Q. If the output signal fromanAMmodulator is given by u(t) = 5 cos 1800 πt + 20 cos 2000 πt + 5 cos 2200 πt , determine:
(a) The modulating signal m(t) and carrier c(t).
(b) The modulation index.
(c) The ratio of the power in sidebands to the power in the carrier.
The present window that is being used.
Q. A negative impedance converter is used, as shown in Figure. Show that the load current i L is given by v in /R, which is independent of Z L . Note that since the load sees a cu
