When a 100-k load is connected to a signal source, the output voltage is 30 mV. If a 10- k resistor is used to load the same signal source, the output voltage is observed to be 10 mV. Find the corresponding Thevenin voltage, Norton current, and source resistance for the particular signal source.
Write the equation for the acceleration as a function of the position change of the platform.
Assume you buy a 1 kOhm resistor with +/- 20% tolerance in its value. You would like this resistor to consume at most 2 W of power, otherwise it might burn. What is the highest power supply in V you would use to power it
If the breakdown voltage increases with temperature at a rate of 40 mV/"C, find the break-down voltage of the diode at room temperature, assuming that the space-charge resistance is 10 C& independent of temperature.
For the open-loop system \(G(s)=y(s)/u(s)=1/[s^{2}(s^{2}+400)]\) design the controller and estimator so that the closed-loop unit step response to a command input has a rise time tr
Find the induced emf as a function of time, for a square wire loop of side length 3m, in the x-y plane with one corner at the origin, due to a changing magnetic flux density B =5xycos(10t)z ˆ Wb/m2
Consider a coffee counter with a single server at which tired students arrive according to a Poisson process. Let the mean arrival rate be two students per ten minutes and assume the serving time is exponentially distributed with an average of 180..
Plot how this absorbed power varies with signal strength W12, and discuss the behavior especially at very small and very large W12. Where does the absorbed power go? -and how does it get there?
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
A)Design a high-pass filter with a cutoff frequency of 40 kHz. Use 0.01 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at the cutoff frequency Give your answer both as ratio (Vout/Vin) ..
An ore car of mass 35000 kg starts from rest and rolls downhill on tracks from a mine. At the end of the tracks, 26 m lower vertically, is a horizontally situated spring with constant 3 × 105 N/m.
Assume you have a receiver with an overall noise figure of 23 dB and a bandwidth of 1 MHz. Assuming the minimum acceptable SNR at the output of the receiver is 6 dB, estimate the minimum detectable signal level in dBm at the receiver input.
a) both stations begin to transmit at the same time b) one station begins to transmit at the first possible moment such that its transmission would not be detected by the other station before it began its transmission
