The line spread function of an imaging system is described by a rectangular box function of width W millimeter (mm), i.e.,
L(x) = { 1, | x | < W/2
{ 0, otherwise
a. What is the resolution of this imaging system in terms of FWHM (full width at half maximum) and in terms of lines/mm?
b. Suppose the field to be imaged contains 3 parallel bars of width W mm, spread nonuniformly, with the darkness profile. Determine the darkness profile of the bars after imaging. Can you still tell all the bars apart? How bars will you see? What will be their respective width?
design and implement a C++ program to simulate a game of Blackjack between two to four players. Your program must incorporate a two-dimensional array to represent the suit and the value of each card dealt to a player,
How many different teams can be organized consisting of two men, two women, and two children? We have the following groups available for team assignments: six men, five women, and four children.
A 100V dc series motor has an armature resistance of 0.2 ohm and field resistance of 0.25 ohm. The motor runs at a speed of 600 rev/min when the shaft torque is 27.14 Nm. Friction and windage losses at this speed are 300W.
A long narrow rod has an atomic density of 5*1028 m-3. Each atom has the polarizability of 10-40 F m2. Find the internal electric field when an axial field of 1 V/m is applied.
Derive the transmission and reflection coefficients for the case of tunneling through a square potential barrier with 0
The output of an exclusive-NOR function is false only if exactly one of the inputs is true. Show the truth table of a two-input exclusive-NOR function, and implement it using AND gates, OR gates and NOT gates.
(a) Determine the minimum required sampling rate fsamp(min). Hence, use twice this value. (b) Draw a block diagram of the system indicating the requirements of each block. (c) Design and write the difference equations of the digital filters needed.
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
Discuss these possible reasons, indicating which are the most important: The field is so young; such different needs; there are so many types of systems; and people with widely different backgrounds are developing.
draw a digital design consisting of 2 input AND gates and three inverters, where an inverter is connected to each of the AND gates input and its output. For each of the four possible combinations inputs applied to the two primary inputs.
an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 96 MHz and deviation of f=20 KHz. A narrowband FM generator with Fc=200 KHz and adjustable deviation f in range of 9 to 10 Hz is available.
You also have frequency doublers, mixers and an oscillator with an adjustable frequency from 13 to 14 MHz. There are also bandpass filters of any specification.A. Draw the block diagram of the system.
