Choose the correct answer: 1. In AM, 50% modulation indicates that 33.3%.11.1%). of the total transmitted power is in the sidebands (0%,50% 2. To obtain coherent detection in AM receiver, an extra signal is added to the modulated signal, this signal called (PLL, IF carrier, pilot carrier, subcarrier). 3. The output spectrum of a modulator includes upper-side, lower-side frequencies, and the carrier frequency. (balanced, standard amplitude, SSB, none of the above) 4. When a signal is multiplied by the unit step function, (the positive time range is suppressed, the negative frequency range is suppressed, the negative time range is suppressed, the positive frequency range is suppressed). 5. DSB-LC requires coherent detection at the receiver, if the type of modulation is modulation, over modulation, critical modulation, none of them). 6. A continuous FT indicates a 7.

If the maximum shift in frequency is 70 kHz and the minimum deviation in frequency of the actual signal is 109.93 MHz, what is the carrier frequency? (110 MHz, 110 kHz, 107 kHz, 102 MHz) 5. TDM of signals requires them to have the same amplitude, sampling frequency, energy). 6. In standard AM, the last step in the transmitter is subtracting, multiplying, dividing). .

Do not use chatgpt or AIarrow_forwardA linear electrical load draws 11 A at a 0.72 lagging power factor./1 153. When a capacitor is connected, the line current dropped to 122 A and the power factor improved to 0.98 lagging. Supply frequency is 50 Hz. a. Let the current drawn from the source before and after introduction of the capacitor be 11 and 12 respectively. Take the source voltage as the reference and express 11 and 12 as vector quantities in polar form. b. Obtain the capacitor current, IC = 12 - 11, graphically as well as using complex number manipulation. Compare the results. c. Express the waveforms of the source current before (11(t)) and after (12(t)) introduction of the capacitor in the form Im sin(2лft + 0). Hand sketch them on the same graph. Clearly label your plots. d. Analytically solve i2(t) – i1(t) using the theories of trigonometry to obtain the capacitor current in the form, ¡C(t) = ICm sin(2πft + OC).
