If a 400-watt carrier is amplitude modulated to a depth of 75 percent, what is the total power in the modulated wave?
Let c(t) = Ac cos (2πfct) and m(t) = cos (2πfmt). It is given that fc 5fm. The signal c(t) + m(t) is applied to the input of a non-linear device, whose output vo(t) is related to the input vi(t) as v0(t) = avi(t) + bvi2(t) where a and b are positive constants. The output of the non-linear device is passed through an ideal band-pass filter with center frequency fc and bandwidth 3 fm, to produce an amplitude modulated (AM) wave. If it is desired to have the side band power of the AM wave to be half of the carrier power, then a/b is
A bandwidth of 10 kHz is required for AM system. If the lowest frequency component in the modulated signal is 555 kHz, carrier frequency in kHz is:
For the modulated signal x(t) = m(t) cos (2πfct), the message signal m(t) = 4 cos (1000πt) and the carrier frequency fc is 1 MHz. The signal x(t) is passed through a demodulator, as shown in the figure below. The output y(t) of the demodulator is
