Why developing software for wireless devices is challenging? List and briefly describe the two (2) reasons given in your textbook for why developing software for wireless devices is challenging.
A typical "deep-cycle" battery (used for electric trolling motors for fishing boats) is capable of delivering 12.6 V and 10 A for a period of 10 hours. How much charge (in columbs) flows through the battery in this interval. How much energy does t..
A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving.
Write the formula for the maximum clock frequency for an n-bit synchronous parallel binary counter. Beyond what value of n is your formula no longer valid. let Ttq denote the propagatoin delay from T to Q in a T flip-flop.
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters:R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms The motor is connected to a three phase, 440-V, 60-Hz supply.
a computer will be used to control flow through 10 pumping stations. the pumps exhibit a surging effect with a period
design a 4 bit register with 4 different kinds of flip flops, that has at least 12 different functions. list clearly the functions. Do something creative, and say exactly your innovation. at least one flip flop should have some input besides a mul..
Determine the work done in carrying a charge -2x10-6C from P1 = (2, 1, -1) to point P2 = (8, 2, -1) (both in cartesians) in the field E = yax + xay (all in SI units) by integrating QE.dL along the straight line connecting the two points. Note: E i..
Explanation of the circuit: Two opamps on the top are the buffer amplifiers before and after sampler. Sampler is a JFET used as analog switch; its gate is driven by the narrow pulse train as specified above. There are two identical active lowpass ..
Assuming that only integer multiples of a unit bipolar transistor having IS = 3 x 10-16A can be placed in parallel, and only a single voltage source, VB, is available (Fig. 4.54), construct the required circuit with minimum number of unit transist..
A new phone company wants to provide very cheap voice-only cell phone capability to 200,000 simultaneous users in San Francisco. They transmit only 8kbs per duplex channel using FDMA (frequency division multiple access) and BPSK (1 bit/Hz).
Two batteries with 1.8 voltage and 10.5 Ohm internal resistance each are connected in series. This battery pack is used to boot a small electric motor with 275 Ohm resistance. Find the power delivered to the motor.
