A battery has a short-circuit current of 20 A and an open-circuit voltage of 12 V. If the battery is connected to an electric bulb of resistance 2 ohm, calculate the power dissipated by the bulb.
Calculate: Critical frequency for the input low pass network, and the output low pass network, estimate the values for Cbe, Cjc, Cbc, and Cje. Concider the resistance of the signal sourceRs to be equal to the 1 ohm resister in series with the source.
Determine log10 0.2 = log10 18/90, and compare to log10 18 - log10 90.
Create a state transition diagram for a simple state machine to detect a positive pulse. You choose either a Moore or Mealy machine. Write a Verilog HDL module for your state machine.
A three phase synchronous generator operates onto a grid bus of voltage 33 kv (line to line). The armature reactance of the machine is 2 ohms per phase and the leakage reactance is 3 ohms per phase.
1. Find the Fourier transform of the signal by hand, using either the de nition of the Fourier transform or properties of the Fourier transform. 2. Use the Symbolic Math Toolbox to nd the Fourier transform and show that the same result is obtained.
Consider a pn junction diode biased at I(D) = 1mA. A sinusoidal voltage is superimposed on V(D) such that the peak-to-peak sinusoidal current is 0.05I(D). Find the value of the applied peak-to-peak sinusoidal voltage if n = 1.5. Repeat problem for..
Determine the 8-bit sign-and-magnitude, 1's complement, and 2's complement representations for each of the following decimal numbers: +36, -84. (Note: Be sure to represent +36 as a positive number and -84 as a negative number.)
Consider the casual LTI system where the output relates to the input by the following differential equation: dy(t)/dt + 2y(t) = x(t) a) Determine the frequency response H(jw).
Consider a gsm uplink.the ms has 100 mw transmit power and the sensitivity of the bs receiver is -105 dbm.the distance between the bs and ma is 500 m.the propagation law follows the free space law up to a distance of dbreak=50m
Using a 100-Ω slotted lossless coaxial cable, it is found that the distances from the load to the first and second voltage maxima are 1 and 11 cm, respectively, and the standing wave ratio S = 2. Find the load impedance.
b) What are the equilibrium electron and hole concentrations at 300K and 500K (hint: You will have to find Nc and Nv at 500K, but it isnt necessary for 300K) c) Why does the mobile carrier concentration increase at high temperatures
One end of a long glass rod (n = 1.3) is a convex surface of radius 4.9 cm. An object is located in air along the axis of the rod, at a distance of 10 cm from the convex end. (a) How far apart are the object and the image formed by the glass rod
