Assume two cables have wire strands that are the same diameter and made of the same material. If one cable has 7 strands and another has 19 strands, which will have more resistance over a mile? Why?
A baseband channel has a bandwidth of 10kHz. A) How do i determine the maximum symbol rate (in kbaud) if the channel is noise free B) How do I determine the channel capacity (in kibits/s) for binary encoding if the channel is noise free
A series-resonant RLC circuit has R = 80 (ohms), L=25mh, and C=10pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a minimum D) What is the magnitude of the impedance at this frequency
Two data streams are coming serially to a system. These two streams are carefully observed and if considering any three bits from each stream, we observe that these two input streams are equal ; the FSM gives a signal to an alarm system.
A flood control project with a life of 12 years will require an investment of $300,000 and annual maintenance costs of $25,000. The project will provide no benefits for the first two years but will save $40,000 per year in flood damage
Design a PLC program and prepare a typical I/O connection diagram and ladder logic program for the following motor control specifications:1) A motor must be started and stopped from any one of three start/stop pushbotton stations.
The loop transfer function of a single-loop negative feedback system is: L(s) = Gc(s)G(s) = K(s + 2.5)(s + 3.2) / (s2(s + 1)(s + 10)(s + 30)) This system is called conditionally stable because it is stable only for a range of the gain K
The gain of the antennas must be increased when the TDMA system described in part (d) is used because the bit rate is higher than with FDMA and the noise power in the receiver is therefore higher
The solution to Power Factor, Two single-phase loads are connected in parallel across a 415 V, 50 Hz supply. One load is rated 130 kW at a power factor of 0.75
Design a decade counter (negative edge-triggered counter) using flip flop circuit that can be used to perform binary counting. Show the timing diagram for the input and four outputs of the decade counter.
The signal given is x(t) =cos(440*2*pi*t) +cos(554*2*pi*t)+cos(659*2*pi*t) Find the complex exponential forier series of the signal and plot k vs Ck for k=-1000 to 1000.
There are three numbers stored in Memory Locations 10-12. Write a machine language program to load each number in the accumulator one at a time. Use the immediate addressing mode to add four to each value that is loaded to accumulator.
A current source of value 2cos(2t) A is used to power a string of 2W lightbulbs. If you wanted to replace this current source with a DC one, but have the same power drop, what DC current should you apply (one decimal place needed)
