A particular inverting amplifier with nominal gain of -100 V/V uses an imperfect op amp in conjunction with 100-k ohm and 10-M ohm resistors. The output voltage is found to be +9.31 V when measured
To keep them running, some users created their own 25 Hz power in the plant using motor-generator sets. A motor-generator set consists of two machines connected on a common shaft, one acting as a moto
Your friends Alice and Bob have two children. You recall that one is a boy. What is the probability that the other is a girl Hint: Think carefully about the sample space.
Consider a vector field, F(r,theta,phi)= ar*cos^2(theta)/r^2 for the volume V of a spherical shell, centered at the origin,with inner and outer radii 1 and 2 meters. a) Evaluate triple integral delta.
a) Evaluate the net outward flux through the closed surface of the unit cube. b) Evaluate also the triple integral over le volume v and check if the divergence theorem is satisfied. F(x,y,z)=ix^2y+j
determine whether the statements are valid or invalid. If a statement is valid, please give a proof as in problem 1. If a statement is invalid, you need only provide a counterexample. If x + y = x +
Write a program to count the number of elements in an array whose bits 3, 4, and 7 are zeros. The array has N 8-bit elements and is stored in memory locations starting from $1000
Given an ideal op amp to implement designs for the following closed-loop gains, what values of resistors (R1,R2) should be used. Where possible, use at least one 10-kohm resistor as the smallest res
An Agilent 33220A function generator is set-up to produce an output of v(t)=5+10sin(2 *100t) at the Output connector. a. Describe how you would increase the frequency to get an (open-circuit) output o
Assume that you are adding two 4-bit numbers. What does a carry-out (in the fifth place) indicate. Does this carry-out indicate something different when we add two positive numbers, a positive and n
The standard method of representing negative numbers in the binary system is with 2's complement notation. Let's start by discussing why this is the case. What are the advantages and disadvantages o
Typical gearing for most bicycles ranges from 30 to 50 teeth on the chain wheel and 12 to 30 teeth on the rear cog. Find how many more revolutions of the pedals the mountain biker will make during 4
Suppose the above device is to be used as an 8-way power splitter (let's say only the top-most input is used). Let the input power be P. Assuming a cross-coupling coefficient of f and ignoring exces
Suppose unchirped Gaussian pulses at f = 1:55 fm are used to transmit binary data. You're given that the fiber dispersion parameter f = 17 ps/km-nm, and the dispersion length LD = 115 km. What is th
Electrostatic scaling: prove that electrostatic force between the two plates of a charged capacitor is a surface force (~L2); How about the stored energy under constant voltage on the capacitor (~L1
