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
A transmitter puts out a total power of 2.09 Watts of 30% AM signal. How much power is contained in each of the sidebands?
A 2 kW carrier is to be modulated to a 90% level. The total transmitted power would be
If modulation index of an AM wave is changed from 0 to 1, the transmitted power
If transmitted power = Pt, modulation index = m, carrier power = Pc, then the total transmitted power in a conventional A.M. system, is given as
Directions: The item consists of two statements, one labelled as the ‘Assertion (A)’ and the other as ‘Reason (R)’.You are to examine these two statements carefully and select the answers to the item using the codes given below:Assertion (A): In amplitude modulation systems the value of modulation index should be around 1.Reason (R): The power carried in the intelligence carrying sidebands increases with the modulation index.
