1. An integral controller has an input range of 1 to 8 V and an output range of 0 to 12 V. If K1 = 12%/(%/min), find GI, R, and C.
2. Design a PD controller with a 140% PB and a 0.2-min derivative time. The fastest signal speed is 1 min. Measurement range is 0.4 to 2 V, and the output is 0 to 10 V.
Consequently, this form of serial data communication is known as asynchronous. Compare and contrast this against synchronous serial data communication, giving an example of a synchronous data communications standard.
A positive-sequence balanced three-phase wye-connected source witha phase voltage of 120 V rms supplies power to a balanced wye-connected load. The per phase load impedence is 40 + 10JΩ.
A step-down transformer has a 120V rms primary voltage applied and a 12V rms voltage is measured at thesecondary. Assuming the transformer can be considered ideal,determine the turns ratio, n.
How can a technician determine whether a compressor is not pumping to its rated capacity?
A circular coil of 200 turns of radius a=60mm, total resistance R=2 ohm, and no self inductance is rotated about a vertical diameter with uniform angular velocity =200 rad/s in a horizontal magnetic flux B of 0.25 Tesla.
From the definition of polarization (p) Perrin equation, and anisstropy (r) introduced by Jablonski, derive the interchangeable relation between p and r.
A particular "1 mA diode", which at 25° C conducts I mA at 0.7 V, is operated at 95°C in a circuit which provides it a constant 100 RA current. What does its junction voltage become if it = 2?
Determine the FWHM diameter of the beam 50 mm from the second lens (ie. 100 mm from the first lens.) A third lens is placed at the point with a focal length off.
Consider a magnetic dipole carrying a current I. a. Calculate the magnetic flux density B at a point P specified in spherical coordinates. Express the answer in terms of the magnetic dipole moment m. Justify all the assumptions adopted.
Show the design of a 2-1 Mux: (a) using a NAND/NAND implementation, (b) using a NOR/NOR implementation. Which would you prefer to build and why Assume that you have all variables and their complements available.
(a) determine the contact resistor that can go on the base if the length of the contact is 10 * Wb. (b) Plot the change in conductance in relation to varying the doping from 1014/cm3 to 1018/cm3 at room temperature. Redo the graph at 77K;
A 1 lb weight is suspended from a 0.005 in diameter wire. The unstrained resistance of the wire, R0, is 270 ohm, and its unstrained length is L0=36 in. The wire's gauge factor is 3.2. a. Calculate the psi tensile stress on the loaded wire.
