1. What is the magnetic flux crossing an infinitesimal surface oriented parallel to the magnetic flux density vector?
2. For what orientation of the infinitesimal surface relative to the magnetic flux density vector is the magnetic flux crossing the surface a maximum?
a. What are the cyclic frequency (in Hz) and period of this signal b. Express this signal in the Quadrature and Sine/Angle forms. c. Express this signal in terms of complex exponentials (hint - use Euler's identity equation).
A flashlight bulb with a potential difference of 4.5 V across it has a resistance of 8.0 ohm. How much current is in the bulb filament?
A short distance system is composed of two identical transmission lines with an amplifier between them. A 1 mW signal is transmitted at one end and is received at the other end with an SNR of 22 dB.
Watts in Cassette Players, A walker's cassette tape player uses 4 AA batteries in series to provide 6V to the player circuit. The four alkaline battery cells store a total of 200 watts-second of energy.
An electric ventricular assist device (EVAD) that helps pump blood concurrently to a defective natural heart in sick patients can be shown to have a transfer function G(s) = Pao(s)/Em(s) =1361/ s2 + 69s + 70.85The input, Em(s) is the motor's armature..
Consider the circuit diagram below. Use superposition to find voltage Vx as drawn. Draw all sub-circuits in your analysis to receive full credit.
Calculate the Fourier Transform of f(t) = 5 sinc(-2t/100), and graph the magnitude and phase as a function of f. If the signal of problem 1 is delayed by 0.1 ms. What is the new Fourier Transform.
four determinations of the pH of a certain solution are 7.90, 7.94, 7.91, and 7.93. Assuming normallity of determinations with mean mhu, standard deviation sigma, find: A. 99% confidence interval for mhu "u"
Some of the particles comprising atoms react to each other in a way that scientists categorize as electric charge. There are two fundamental types of electric charge: positive and negative.
The sum constraint in (6.6) applies because the two users send inde- pendent information and cannot cooperate in the encoding. If they could cooperate, what is the maximum sum rate they could achieve, still assuming individual power constraints P..
