1. What is the basic differences between:
a) Volatile and nonvolatile memories.
b.) EPROM and EEPROM.
c.) SPAM and DRAM.
d.) PLD and ROM.
e.) CPLD and FPGA
2. Draw a block diagrams showing enamel, address, and data lines for each of the following: 2732, 2764, 27128, and 27256.
3. Draw a schematic for a 6k x 8-bit memory array using a minimum number of 2732's. What are the higest and the lowest memory addresses (in hex) in the array?
The 741 op amp is usually modeled on specification sheets as a voltage amplifier having the following parameters: Rin = 1 M, Av = 100,000, and Rout = 100 Using this information, develop equivalent circuits for the 741 as a current amplifier
The signal x(t) = sin(2pi(100)t),was sampling with sampling period T=1/400 second, 1- obtain a discrete time signal x(n) 2-what is the maximum sampling period which allows perfect reconstruction
A wattmeter connected into the line gives a reading of 2765W. If a capacitor have a reactance of 30ohms is connected in parallel with the motor. Calculate the total reactive power absorbed by the capacitor and motor.
A series-resonant RLC circuit has R = 80 (ohms), L=25mh, and C=10pF. A) Sketch and label the circuit. B) Find fo, the resonant frequency. C) At what frequency is impedance a minimum D) What is the magnitude of the impedance at this frequency
The frequencies of the tones are 100 Hz, 300 Hz, and 450 Hz. The sampling rate is 1 kHz. Describe a low pass, a band pass, and a high pass filter that could be used to detect the individual tones.
Create an array, array1, that has the last 14 elements of which the first element is 49 and the last element is 10. THen using the colon symbol create a new array, array 2, whcih has 8 elements. the first 4 elements of array 2 are the 4th through ..
An engineer decides to take 600 samples at sampling frequency 9000Hz. A Fast Fourier Transform (fft) program was applied to obtain the frequency spectrum of the signal. What is the frequency resolution,df, for the analysis
A uniform electric field exists in the region between two oppositely charged plane parallel plates. An electron is released from rest at the surface of the negatively charged plate and strikes the surface of the opposite plate
In this project we will consider the control of a synchronous generator supplying electricity to the grid.
A regenerative gas turbine has compressor and turbine discharge temperatures of 350K and 700K respectively. Draw and label schematic and T-S diagrams showing the relevant states.
Analyse and Model Engineering Situations and Solve Engineering Problems using Laplace Transform
A machinable grade of aluminum is to be milled on an NC machine with a 20 mm diameter four tooth end miling cutter, Cutting speed = 120 m/min and feed = 0.008 mm/tooth. Convert these values to rev/min and mm/rev.
