For the vector field E = 5exp(-2r)rˆ - 3rzˆcalculate the divergence in cylindrical coordinates. Verify the divergence theorem for the cylindrical region enclosed by r=2, z=0 to 4.
Networks play an important role in telecommunications. Networking has a tremendous effect on people's everyday lives. Identify the necessary components required in designing a wire-based and wireless network.
Phase current - Neutral Grounded Assume that the load is star connected with the neutral grounded. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Calculate and plot the Phase a current Ia using Fourier techniques.
What is the net number of electrons per second that pass through the cross-section of a wire carrying 5 A of dc current The current now is due to electrons, and the magnitude of the charge of each electron is 1.60×10?19 C.
(a) Using superposition, determine the voltage labeled vx in the circuit represented. (b) To what value should the 2 A source be changed to reduce vx by 10% (c) Verify your answers by performing three dc sweeps in PSpice.
A silicon NPN bipolar junction transistor is to be used as an amplifier. What are the required bias conditions for this to occur If the emitter voltage is -3V, pick an acceptable base voltage and an acceptable collector voltage for the transistor ..
In addition, the distance between the components of the exciton is always such that there are intervening semiconductor atoms. Thus e in the Bohr formulation must also be replaced by Ks e0, where Ksis the semiconductor dielectric constant.
Design a second-order Butterworth bandpass filter with the following specifications: Bandwidth:400HzCenter frequency: 2000Hz Determine the transfer function and realize it using the Sallen-Key circuit topology.
Design a simple unipolar drive circuit such that the electrical time constant is 2 msec at phase turn-on and 1 msec at turnoff. The stepping rate is 300 steps per second. A three-phase variable-reluctance stepper motor has parameters.
Two stations running TCP/IP are engaged in transferring a file. This file is 104KB long, the payload size is 100 bytes, and the negotiated window size is 2000 bytes. The sender receives an ACK 900 from the receiver.
An npn differential amplifier with I = 0.5 mA, Vcc = VEE = 2.5 V, and Rc = 8 kohm utilizes BJTs with B=100 and VBE=0.7 V at Ic = 1 mA. Assuming that the bias current is obtained by a simple current source
A Si p+-n junction has a donor doping of 5*10^16 cm^-3 on the n side and a cross sectional area of 10^-3 cm^2. If τ(p)= 1μs and D(p) = 10cm^2/s, calculate the current with a forward bias of .5V at 300K.
Create a Verilog module that implements 4 bit full adder-subtractor with overflow detection. You may use Verilog bitwise operators and gate primitives, but no mathematical operators or behavioral Verilog syntax.
