A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function of v Q volts, where Q is in gal/min, and an output impedance of 2.0 kO. Tests show that the output of the sensor has 60 Hz noise of 0.8 V rms. Design a signal-conditioning system, including noise filtering, and evaluate your design as follows.
a. Plot output voltage versus flow, and comment on the linearity.b. Determine the noise on the output as percent FS.
In the presentation, the presenter, Mr. Rob Tucker discussed three types of disturbance mitigation responses or measures. List the three mitigation types and give a short definition of each of the mitigation type.
Given a circuit with applied voltage v(t)=14.14cos(ωt)(V) and a resulting current i(t)=17.1cos(ωt-25)(mA). Determine and draw the complete power triangle.
A Si sample is uniformly doped with phosphorus at 5 E 16 cm^-3. We make a p-n junction by implanting boron atoms into the surface layer. The implanted depth is 0.15 µm. What should the surface concentration of the boron implant
An amplifier operates from -5V and +5V balanced power supplies. It provides a 3.2-Vpeak sine across a 150 ohm load when provided with a 0.2-V peak input from which 2.0mA peak is drawn. The average current in each supply is 20mA.
A drug test for college athletes will result in three possible test results: Positive, Negative or Inconclusive. For a drug user the probability of these outcomes is 0.65, 0.06 and 0.29 respectively.
Design a synchronous counter with a count sequence of all prime numbers between 3 and 15. Give the excitation equations. Map any unused counter states into the state whose output is the largest prime number output by this counter q.

A three-phase, 60Hz, wye-connected synchronous generator has balanced line-to-line voltages of 480V at its terminals. The generator is supplying power to two balanced and delta connected, three-phase loads. the first load is made up
for the polynomal function P(x) = x^2 / 3 + x^2 - 8x + 1 find all relative extrema, the inflection point, the interval on which P is concave down
In US, electric wires are classified based on their gauge numbers. The larger the gauge number is, the smaller the diameter of the cross-section of the wire becomes. You are given four different types of wire with gauge numbers 1, 3, 7, and 8.
Determine experimentally the value of a resistor that when placed across the battery will make a measurable change in measured battery voltage. Keep the voltage decrease from open circuit value to 10% or less.
A particular communications system has 2 identical receiver stages connected in cascade, each with gain 7 dB and noise figure 4 dB. Compute the noise figure of the combination assuming the stages are impedance matched.
