With the table of standard resistor values given in Appendix A, design a voltage divider to provide the following approximate voltages with respect to ground using a 30 V source: 8.18 V, 14.7 V, and 24.6 V. The current drain on the source must be limited to no more than 1 mA. The number of resistors, their values, and their wattage ratings must be specified. A schematic showing the circuit arrangement and resistor placement must be provided.
The transmit antenna gain is 2.1dB, and the receive antenna gain is 1.6dB. The received is 18Km away from the transmitter. The receiver has a Noise Figure of 8dB, Bandwidth 1.7 MHz and the Data Rate is 640K bps. You may assume T0 = 290K.
(a) If a motor at the end of a transmission line has a reactance of 8 ohms per phase, what is the maximum power which the machine can develop, given that the sender voltage is 4kV and the induced voltage Eo is also 4kV.
let a character stream fromthis source be Huffmancoded. Then, let groups of consecutive four message bitsbe encapsulated into 8-bit SEC-DED Hamming code words.Suppose the following two Hamming are received:0101111001100001.
Determining how to use the function fft to find the DFT coefficients X[k] of x[n] in Matlab. Also, how would you plot the magnitude of X[k] in Matlab?
From the foregoing data, calculate the surface temperature, Ts, and the heat flux at the exposed surface. Using the surface heat flux determined in part (a), estimate the surface temperature by applying an appropriate boiling correlation.
The dielectric constant of a doped GaAs can be expressed as Er=11.56+j0.001 at wavelength lambda 1550nm.Evaluate the propagation loss(in dB/Cm) due to absorption when light(lamda = 1550nm) propagates in the GaAs.
1. What is the purpose of core in hollow solder wire 2. What is tinning, and why is it important 3. Why is safety so important when soldering 4. Why has lead-free solder replaced lead-based solder Be sure to properly cite any sources of information.
What observations can you state about electrical conductivity from observing these pictures? Based on the pictures, list the solutions that based on conductivity, ordered from best to worst.
If a series 50-kΩ resistor is used, find the values of L and C.
Three identical impedances of (12+j15)ohms are connected in wye to a 550V balanced three phase source. Determine, (a)the magnitude of the line currents. (b) the total power dissipated for the three phases. (c)the total reactive power. (d)the power..
Sometimes the partial fraction expansion is not needed in finding the inverse Z-transform- instead the properties of the transform can be used. Consider the function F(z) = z+ 1/z^2(z - 1) a. Determine whether F(z) is a proper rational function as ..
Construct a 2 rung ladder schematice with an AC source with overload protection in the main line, the schematic will contain 1 rung with a lamp load controlled by a N.O. Push button. On the second rung there will be a N.C.
