- Decompose using relationships 3 S(+) = 50 sin ³ (500πiz)arrow_forwardA linear electrical load draws I₁ A at a 0.72 lagging power factor. 11 = 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 = I2 − I₁, graphically as well as using complex number manipulation. Compare the results. c. Express the waveforms of the source current before (i₁(t)) and after (i2(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, ic (t) = 1cm sin(2´ft + 0c). Compare the result with the result in Part b.arrow_forwardI need a solution from an expert without artificial intelligence. Choose the correct answer 1. The convolution of two signals in time domain is equivalent to (addition, subtraction, multiplication, division). 2. The Fourier transform of non-periodic signal is random). 3.

- I need a solution from an expert without artificial intelligence. Choose the correct answer: 1. In AMI code, the shapes of "1" and "O" are, bit dependent, not related to each other). 2. In FDM the guard band is used to decrease, maintain, not related to). 3. Higher number of levels in PCM produces (the same, opposite to each other, next the overlap between FDM signals. (increase, (higher quantization error, less number of bits per sample, lower quantization error, the same number of bits per sample). 4. 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) Fc 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). .

The signal x(t) is band-limited by an ideal analog low-pass filter with a cutoff frequency fc. The signal x(t), ideally sampled at a rate of 80 Hz, is reconstructed using an ideal low-pass filter with a cutoff frequency of 40 Hz, resulting in the signal y(t). a) Plot the spectrum of y(t) if fc = 40 Hzb) Plot the spectrum of y(t) if fc = 20 Hzarrow_forwardQ1 Q2 03 Find the total steel reinforcement (As) and the number of 20 mm bars that must be spread along the long direction of rectangular concrete footing of width B-2.10m which supports concrete column dimensions (0.4x 0.4) m.
