Design a 1024x16 RAM using the 256x8 RAM blocks and neccessary combinational circuit. Note that, 256x8 RAM block has 8 bit data (DATA), 8 bit address (ADRS), chip select (CS), read/write (R/W) inputs and a three-state output bus.
A 450 kW motor operating 73% Power factor lagging is connected to a 120V(rms), 60Hz line. (a) Sketch and label the power triangle for the motor. (b) Find the rms current into the motor.
If we want to correct the power factor to 0.9 lagging, what is the value of Q we need to inject.
Develop the pseudo-code below for a program that will retrieve 2 bytes (NUM1 and NUM2) from memory, determine which is closest to the numeric value 50, and indicate the result by setting a variable named "CLOSEST" to 1 (if 1st byte is closest) or ..
Suppose you are working for an aircraft company on a positioning control system that controls the position of the landing for their aircraft. This positioning system requires a feedback signal from a position sensor.
A Si PIN photodiode has an i-Si layer of width 20 µm. The p+ layer on the illumination side is very thin (0.1µm). The PIN is reverse biased by a voltage of 100 V and then illuminated with a very short optical pulse of wavelength 900 nm.
Ziegler-Nichols Open Loop Tuning Often, when working with a faster loop, many people will opt only for a PI control philosophy
Absorption loss of metal shielding, A plane metal shield offers an absorption loss of 30 dB at a frequency of 10 kHz to normally incident radiated emission.
Calculate the total complex power, total current drawn and the total power factor and Y-connected load with an impedance of (1+ j 6) ohm per phase,
An infinitely long line charge (Pl= 21 PI nC/m) lies along the Z-axis. An infinte area sheet charge PS= 3nC/m^2 lies in the X-Z plane at a distance Y =10 m. a) Using Gauss' law find the field E due to the line charge.
write an 8051 program that would generate a 200khz, 50% duty cycle, square wave at P1.0.Use Timer 0 for the delay. Ignore the overheads cycles due to the instructions in the loop. Assume 12 MHz clock. All data must be hex.
determine that the total field B within the sample is one tesla. Calculate M and determine what percentage of the volume now consists of domains with magnetization parallel to the field.
How many decimal characters (including a possible minus sign) will be required to represent in decimal, sign-magnitude form numbers which are represented using twos complement 24-bit numbers in binary
