Think about how you adjust the water temperature coming from a single nozzle using the hot and cold hand valves in a kitchen faucet. Construct the block diagram of an automatic system as follows:
The desired water temperature is selected by the user, perhaps by a knob and LCD readout. One hand valve turns on the cold water. The hot water valve is automatically set to keep the temperature at the selected value.
Describe what elements would be necessary to do this using (a) analog control and (b) computer control.
A, B, Bin, D and Bout are respectively the minuend, the subtrahend, the BORROW-IN, the DIFFERENCE output and the BORROW-OUT in the case of a full subtractor.
Design a circuit with one output f and four inputs x1, x0, y1, andy0. Let X = x1x0 be a 2 digit binary number. X can have fourpossible valuations (X=x1x0), namely, 0 = 00, 1 =01, 2 =10, and 3 =11.
What is the relationship between air-to-air heat pump heating capacity and outside air temperature?
The functional frequency n of a stretched string is a function of the string length L, its diameter D, the mass density r, and the applied tensile force T. Suggest a set of dimensionless parameters relating these variables.
The samples are binary PCM encoded into n bits whichare transmitted using two waveforms S1 (t)=1.414 sin(w1t) and S2(t)=1.414 sin(w1t) + 1.414 cos(w1t) where t is between 0 and Tb,and the a priory probability of S1 is p(s1) = 0.4.
A cyclotron used to accelerate alpha [articles (m=6.55 x 10^-27kg, q=3.2x10^19C) has a radius pf .50, and a magnetic field of 1.8T (a)what is the period of revolution of the alpha particles (b)what is their kinetic energy
Two plane waves that are spatially and temporally coherent propagate in the x-z plane and intersect at an angle such that each wave makes an angle (please see the attached file) with the z-axis. The figure below shows the k-vectors associated with..
The current density inside a long solid cylindrical wire of radius a is in the direction of central axis and varies linearly with the distance from that axis r according to J=J0 r/a.
Let x(t) = cos(3/4(t+1/2)+1/4) a. Determine the frequency, the period of x(t) b. Given another signal, y(t)= sin(3/4(t+1)+3/8), is y(t) identical to x(t) Why
Use this to prove that at any point P there are three orthogonal directions (the principal stress axes at P) with the property that the surface force on any surface normal to one of these directions is exactly normal to the surface.
Determine the values of the lumped parasitic capacitor and inductor in a 5 ft long two-wire transmission line with air dielectric Each wire has a diameter of 1 mm and the separation between the wires is 1 inch.
The loop transfer function L(S) of a single-feedback-loop control system is given below. Sketch the Nyquist plot of L(jw) for w=0 to w=infinity, Determine the stability of the closed-loop system.
