A temperature sensor measures from -44 f to 212 F with an output of 0-5 v. If an 8 bit ADC is used, what is the converter output for a temperature of 25 F
Bit 4 of Port B is connected to a switch that normally outputs a zero. Monitor this switch to detect a change from zero to one. Immediately when it becomes one, call a function to toggle Bit 5 of Po
What is the function of the enable control input of a tri-state buffer If the output of two or more tri-state buffers is connected to each other, what is the restriction on enable control input line
A p-n junction is made by doping Silicon with donors and acceptors. The doping at the p side has a uniform density of NA, but the doping density at the n side is not uniform and changes linearly wit
Construct a 4-to-16-line decoder with five 2-to-4-line decoders (74LS139A). Use a block diagram for components and clearly show your address select variables.
The collector current was measured for different values of load resistance. It was noticed that the collector current was pretty much constant for the first 1900 ohms and then it fell drastically.
In spherical Coordinates the potential of a dipole lacated at the origin is given by: a) use \(E = -grad \phi\) and the above to calculate E for a dipole located in free space.
Consider the first-order linear differential equation y(t) + 5 (dy(t) / dt) = x(t) Compute the zero-input response (general solution of the homogeneous equation) to find the system-specific part of t
A 230kVA, 2300/230V, 60 Hz, step-down transformer has the following parameters. RH =1.2-ohm, XH =3-ohm, RL =12m-ohm, XL =30m-ohm, Rh+c=2k-ohm, , Xm =1.8k-ohm. If the transformer operates at half loa
a. Convert all the per unit values to a common kVA of 100 and transmission side voltage base of 2500V b. To maintain one per unit voltage at rated load, find the per unit generator voltage needed.
Suppose you have a 2 kW electric heater rated for 220 volt operation, which you intend to operate at a reduced power dissipation of 1kW. Calculate the proper amount of voltage you would need to achi
define hue (h) in the h-i-s coordinate system. outline how the formula for computation of hue from R-G-B coordinates of a color point may be derived (detailed derivation is not required)
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the prec
Design a logic circuit, LOGARITHM that converts an input number X to its logarithm, log(X). Input X is given as an unsigned real number such that, 1.00<=X<=7.75, using fixed-point fromat with
Reduce the two functions given below and implement them using fewest 8x2 ROM's. Draw a neat labeled diagram showing interconnection between the ROM's address and data lines, and content of each ROM.
Three positive point charges, each with q = 3 nC, are located at the corners of a triangle in the x-y plane, with one corner at the origin, another at (2 cm, 0, 0), and the third at (0, 2 cm, 0). F
A museum has three rooms, each with a motion sensor (m0, m1, m2) that outputs 1 when motion is detected. At night, the only person in the museum is one security guard who walks from room to room.
Using MatLab, create and graph the pairwise convolution of the following functions (i.e., A must be convolved with B, C, D, and E, individually. B must be convolved with C, D, and E, individually, E
noncausal, linear, and time-invariant. Determine the impulse response for the system and verify that an LTI system defined by the impulse response you determined satisfies the difference equation.
