Create an Etch A Sketch using the video screen as a the display and 4 toggle switches as movement buttons.The program will start the cursor in the middle of the screenand will draw "*" when a move is given. THe cursor should be ableto move in any direction (N,S,W,E,NE,SE,NW,SW). Also, if the cursorreaches the end of the screen it should wrap around to the otherside of the screen. If no direction is designated, the cursorshould stay put. Also, the system should show the direction selected on a set of 8 LEDs. When the cursor moves thecorresponding LED should light up.Draw, Erase, and Move modes via keyboard are required. Depending on the mode selected, the program should draw a character on movement, erase a character on movement, or just move the cursor.
For an armature-control DC motor the following parameters are given: ea=22V, f=5x10^-3 onz-in/rad/sec, J=4.27X10^-4 in-onz-sec^2, La=0, Ts=10 onz-in (stall torque), wo= 480 rad/sec (no load speed), K=7.66 in-onz/amp.
A coaxial line is filled with a very slightly lossy material with a relative dielectric constant of 5 The line would have a characteristic impedance of 100 ohm if it was air-filled. (a) What is the characteristic impedance of the dielectric-filled li..
Let the component at Omega(C) = 2pi* 3000 be the corrupting signal. Design an appropriate lter to lter out this component of the input. You can use fir1 command for this. Plot the frequency response of this lter.
Describe how an inductor is practically consumed and what are the problems with practical inductors
A sample of lightly doped GaAs has a room temperature conductivityof 4.04X10-9[S/cm]. If it is known that the electron andhole mobilities areμn=8500[cm2/V·s], andμp=400[cm2/V·s],respectively
A uniform plane wave propogates in the positive z direction with a frequency of 20 MHz. A probe is at z=0 m measuring the phase to 98 degrees and another probe at z= 2 m measures the phase to be -15 degrees what is the relative dielectric constant..
The following 4 differential equations describe mass spring systems. Identify each system as either undamped, overdamped, underdamped, or critically damped (Justify your answer). Determine the angular frequency and period for the undamped and the ..
An infinite grounded conducting tube of radius 10cm is centered on the z axis. A concentric charged tube of radius 6 cm has a surface charge density of 24 uC/m2. A 1m long section of the charged tube is compressed to change its radius to 3 cm.
The transform of the Gaussian pulse g(t) = exp(-πt2) is exp(-π f2). Find thetransform of the modified pulse g(t)= exp(-100πt2). b) Find the bandwidths of the original and modifiedpulses using G(fBW)= .707 G(0). (Hint you have to usethe natural log..
The basic column control system shown in Figure is somewhat more complicated than the basic neutralizer control system
A 1φ, 440 V, 80 kW load, having a lagging power factor of0.8 is supplied through a feeder of impedence 0.6 + j1.6 Ω anda 1φ, 100 kVA, 220/440 V, 60 Hz transformer. The equivalent impedance of the transformer referred to the high-voltage side is 1...
