A separately excited dc motor turns at 1200rpm when the armature is connected to a 115V source. Calculate the armature voltage required so that the motor runs at 1500rpm.
Draw a state diagram for a synchronous sequence detector that will detect every occurence of the sequence 111001 in a serially transmitted message of any length. The sequence detector should detect overlapping sequences as well as individual occur..
Using the Quine-McCluskey's method, find the SOP and POS solutions for the function below, and verify that they match with the Karnaugh map solutions. f (a,b, c, d) = \(\sum m(0,1,6,15)+ \sum d(3,5,7,11,14)\)
1. Obtain a minimal hazard free SOP expression for f(A,B,C,D)=fm(0,1,5,6,8,11,13,14,15),d(2,3,10). 2.Implement f(A,B,C,D)=åm(0,4,5,7,10,13,14,15),d(1,2,9) using a minimal number of 1-of-2 MUXs and NOT gates (if needed).
A trough is 8 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x^{8} from x=-1 to x=1 . The trough is full of water. Find the amount of work in foot-pounds required to empty
The average noise power per unit bandwidth measured at the front end of an AM receiver is 10^(-3) watt per Hertz. The modulating wave is sinusoidal, with a carrier power of 80 kilowatts, and a sideband power of 10 kilowatts per sideband.
If a logic circuit with I_OH = 4.5 V is driving and LED with a 330 ohm limiting resistor, what is the current rating for the LED if the forward voltage drop is 1.8 V
MOSFET Amplier Sketch the 4-resistor bias network for an amplier with an n-channel enhancement-mode MOSFET, with R1 = 1Mohm ; R2 = 1:5Mohm ; RD = 75kohm ; Rs = 39kohm ; K = 25microA/V2 ; VDD = 10V and Vto = 1V.
Given a voltage of 100 volts with a phase angle of 0 degrees, applied across an impedance of 50 ohms at an angle of +30 degrees. This is an inductive impedance - not TOTALLY inductive, but more inductive than capacitive.
a) It is required that the propagation delay be limited to 60 psec. Find the required device widths b) Find the High and Low noise margins, i.e. NMH and NML. c) What is the peak current drawn from VDD during switching of the inverter What is the aver..
