A plane wave is propagating along the z direction in a medium witha propagation coefficient (gamma) equal to (0.004+j2.5)
a) What is the phase shift (in degrees) in the electric fieldfor two points along the z axis separated by 10 m.b) What is the value of the wavelengthc) How much is the attenuation of the magnetic field when the wavetravels a distance of 15 m. Give the result in Np and dB.
GivenEx = E^+ exp(-j gamma z)
A 60 Hz, three-phase, transposed transmission line has the following parameters: Z = 13.114+ j52.952, Y = j0.311/1000. The sending-end line-to-line voltage is 161 kV. The total receiving-end load is represented by ZL =143 with an angle
when an AC source is connected accross a 12.0 resistor,the rms current in the resistor is 8.00 A find (a) the rms voltage accross the resistor,(b) the peak voltage of the source , (c) the maximum current in the resistor
Overflow occurs when a result is too large to be represented accurately given a word size. Underflow occurs when a result is too small to be represented correctly (for example, a negative result while doing unsigned arithmetic.).
(Combinational Integer Multiplier) Draw the schematic for a 3-bit com- binational multiplier designed using partial product accumulation. (A,B are 3-bit inputs and S is a 6-bit output.) Use half/full adders in addi- tion to logic gates to build th..
A linear time-invariant continuous-time system responds to the following inputs with the corresponding outputs:Ifx(t) = u(t), then y(t) = 2(1- e^-t)u(t) and if x(t) = cost,then y(t) = 1.414 cos(t - pi/4).
The range of an analog signal is 2 Vpp, and the samples of this signal are being quantized. The quantizer-output word size is 10 bit. What is the quantization interval Q
Suppose when a baseball player gets a hit, a single is twice as likely as double which is twice as likely as a triple which is twice as likely as a home run. Also, the player's batting average, i.e., the probability the player gets a hit, is .300.
How many decimal characters (including a possible minus sign) will be required to represent in decimal, sign-magnitude form numbers which are represented using twos complement 24-bit numbers in binary
a cost to produce, P, of $4.00. If we were able to reduce this to $3.55 through greater attention in the design, and if the cost to improve the design (in NRE) is $35,000, how many units must we sell to recover the increased design cost
Design the electrical system for a shopping center with 500,000 square feet at least 30 spaces of three different sizes (5,000, 10,000 and 25,000 sf). They may be offices, banks, restaurants and shops.
Asuuming that an 8-bit ADDC channel accepts analog input ranges from 0 to 12 volts, determine the following: a) number of quantization levels b) step size of the quantizer c) Quantization level when the analog voltage is 9.25 volts
A p-n junction solar cell has Voc = .5 V and Jsc = 20 mA/cm2. A second cell of same area has Voc = .6V and Jsc = 16 mA/cm2. Assuming both cells obey ideal diode equation find the values of Voc and Jsc when connected in parallel and series
