Consider an object that has homogeneously textured surface with maximum spatial frequency of (fx,fy)=(3,4) cycle/ meter and that is moving at a constant speed of (Vx,Vy)=(1,1) meter/second. What is the temporal frequency of the object surface at any point? What are the results for following speeds(in meter/second):(4,-3),(4,0),(0,1)
An AC sine wave is applied to the input of a full wave rectifier. The output of the full wave rectifier is then applied to a half wave rectifier.
The resistance per 304.8 m of copper wire uses in the extension cord of AWG 14,12,10,8 and 6 are 2.58,1.62, 1.02, 0.64 and 0.41 respectively. Assume a 2% allowable voltage drop. Show all working .
e) What is the value of C such that the energy stored in the capacitor equals the energy stored in the inductor f) How much energy is stored in the 3.9?F capacitor Use the formula for the energy. g) What is the power dissipated in the resistors
A 3-D cubic unit cell contains four atoms whose centers are positional halfway up along each of the vertical cell edges and one atom each centered in the middle of the top and bottom faces.
b) What are the equilibrium electron and hole concentrations at 300K and 500K (hint: You will have to find Nc and Nv at 500K, but it isnt necessary for 300K) c) Why does the mobile carrier concentration increase at high temperatures
A 15 hp, 209V,three-phase,six pole, Y-connected induction motor has the following parameter values per phase: R1= 0.128 ohm, R'2=0.0935 ohm Xeq- X1 + X'2 = 0.49 ohm. The motor slip at full load is 3%, and the efficiency id 90%.
Two DTEs are communicating via modems and RS-232C interfaces over a half duplex link. Data transmission is one directional with each message of length M. After a message is transmitted, the sender waits for a CTS message.
Let x(t) = u(t) u(t 1).Find the average signal y(t) using the above integral. Let T = 1. Carefully plot y(t).Verify your result by graphically computing the convolution of x(t) and the impulse response h(t) of the averager.
Design a current divider that will provide a 1/3-2/3 current splitting ratio. Use resistance in kilo ohm range. Redesign the current divider so that the resistors are less than 100 ohms but maintain the same 1/3-2/3 splitting ratio.
The maximum voltage that James can apply to this capacitor is limited by Vmax = Kd, where K is the breakdown strengh of the dielectric. deriven an expression for the maximum energy that can be stored in this capacitor in terms of K and the volume ..
