Consider a cylindrical cavity of diameter D=100 mm and depth L=50 mm whose sidewall and bottom are diffuse and gray with an emissivity of .6 and are at a uniform temperature of 1500 K. The top of the cavity is open and exposed to surrounding that are large and T=300K. a) Calculate the net radiation heat transfer from the cavity, treating the bottom and sidewall of the cavity as one surface (qa). b) Repeat a treating the bottom and the sidewall as two surfaces (qb) c) Plot the percent difference between qa and qb as a function of L as L ranges from 5 to 100 mm.
In addition, you have a 32-Kbyte Flash chip, a 16-Kbyte SRAM chip, and a 16 KByte DPRAM chip. You want to locate the FLASH chip right in the beginning of the address space, the SRAM chip just after it, and the DPRAM at the end of the address space..
Find the transfer function and the difference equation for a 2nd -order FIR filter that has unity d.c. gain, but for which the given input x(k) produces zero forced response. (Your filter will have a "notch" at the given frequency, and H(1) =1.)
Create a block diagram of the electronics of the proposed vehicle. Include enough detail on each components and number of wires between each subsystem.
A production plant needs a counter that will count 4,000 items before resetting and recycling. How many flip-flop stages would this counter require
A string of Christmas tree lights of eight (6W, 15V) bulbs connected in series. a) What current flows when the string is plugged into a 120V outlet b) What is the resistance of each bulb
A BJT is operating at a collector current of 1mA ,when Vce=1v and it has early voltage of 75v.If Vce is increased to 11v,find collector current
Write a c program that reads in ten integers from the user on a single line, and determines and prints the largest and the smallest integers in the group. If either the largest or smallest integer is a prime number, have your program indicate this..
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
How many turns are required for a circular loop of 100-mm radius to develop a peak emf of 10mV if the loop rotates 30r/s in the earth's magnetic field Take B = 60E-6T.
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as well as to reduce the receiver power consumption.
Suppose a linear circuit contains a voltage source and a current source. When the voltage source is set to 10V and the current source is set to 10 mA, the output voltage is 1V. When the voltage source is set to 10V and the current source is set to..
For a Wien-bridge oscillator Given R = 20Kohm and C = 10nF what is the frequency of oscillation Given a required frequency of oscillation of f = 3kHz and R = 5kohm, what should the value of C be
