A 60-Hz, 765-KV three-phase overhead transmission line has four ACSR 900 kcmil 54/3 conductors per phase. Determine the 60-Hz resistance of this line in ohms per kilometer per phase at 50 degrees Celsius.
A 100 mile , 300kV, 60Hz transmission line has a reactance of 0.8 ohm per mile and a distributed capacitance of 200,000 ohms per mile. Draw a equivalent circuit phase at the sender end when the receiver is open. What is the reactive power supplied..
What is the effective data rate of this transfer (not counting the time for reading or writing the DVDs)?
Four frequencies are applied at the input of a non-linear amplifier. Write down all of the frequency components at the output of the non-linear device. Write down only the first three harmonics. Frequencies of 1205Khz, 1200Khz, 1195Khz
Wavelength and Frequency, The downstream information (from the network to the customer) is transmitted at a wavelength of 1550 nanometers and the upstream information
A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.
Sometimes audio (or any) signals x(t) are decomposed into a sum of sinusoids. Consider x(t) the sum of three sinusoids of frequencies 518Hz, 730Hz, and 524Hz whose amplitudes are 1/2 of their corresponding frequencies.
calculate the convolution (x1[x]*x2[k]) for the following pairs of sequences: a-) x1[k]=u[k+3]-u[k-2] and x2[k]=u[k+5]-u[k-4] b-) x1[k]=0.5^k u[k] and x2[k]=cos Pi*k u[-k]
Mobile IP was intended to work with legacy correspondent hosts and legacy applications. However, some advantages may be gained if correspondent hosts are aware of mobility in certain ways.
A hybrid communication system uses both AMSC and FM. The information signal a(t) is first AMSC modulated with the subcarrier frequency 1000 Hz. Then it passes through an FM modulator with the carrier frequency 10Mhz.
Using Multisim, design a mod-100 BCD counter that drives a 2-digit, 7-segment display. The count sequence will be 0 through 99. Blank leading zeros in the tens digit of the display.
Write the expression for the current through the capacitor after the switch is closed. The circuit is a 60 Volt circuit
