A 200 resistor, a 10 mH inductor and a 4.7 µF capacitor are connected in a series circuit. a. Is the circuit overdamped, underdamped, or critically damped b. Write the characteristic equation an
Find the Laplace transform of a rectangular voltage pulse that is 0 V until time 0 s, then jumps to 5 V and stays there until time 2 ms, then returns to 0 V and stays there after time 2 ms. Hint: ex
Determine the initial stored charge. Determine energy of the capacitor. If this capacitor is discharged to 0 V in a time interval of 1 s, find the average power delivered by the capacitor during th
Develop with MATLAB, a fuzzy control system for controlling the power of a motor (0-350 rpm) based on the supported load (0-1700 lbs) thereby that at greater load develops more power. The system mus
A computer employs RAM chips of 256 x 8and ROM chips of 1024 x 8. The computer system needs 2K bytes of RAM, 4K bytes of ROM, and four interface units, each with four registers. A memory-mapped I/0
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any basic circuit element. State the values of
For input signal voltages between these limits, the input should pass unaltered to the output. The peak current drawn from the input source may not exceed 1mA. You may use any circuit component we'v
Design a circuit to capture the pressing of buttons (momentary switches). The circuit should have two LEDs "A" and "B", and two buttons, "A" and "B". Whichever button was last pressed should determi
The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asser
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-relu
The amplifier is connected to the handset antenna which has an impedance of 35 + j10 at one unspecified operating frequency. Find the inductive reactance and capacitive reactance needed to match the
Find the noise temperature for a Cal-Amp C-Band 140105-1 low noise block down converters (LNB) for satellite TV. What is their equivalent series input resistance, and what implications does this hav
You are designing a 2.4 GHz receiver with a 140 MHz IF. System design constraints require that the local oscillator power be minimized to reduce the potential for interference to other systems as we
The tuning control is required to provide a uniform, linear change in frequency for a fixed rotation of the knob, e.g., 25 kHz per revolution at any operating frequency. You are considering th
The receiver uses a 10.7 MHz IF. For cost, power, weight and size reasons, it is desirable to use a single clock oscillator that will provide the frequency reference for the synthesizer, as well as
Compute the power levels of the 2nd, 3rd, and 4th harmonics relative to the fundamental output signal for the Class C amplifier. compute the Fourier coefficients for the harmonics of the clipped sin
Assuming a 24 dB link margin is needed to account for fading and loss due to heavy rainfall on the longest link, while 12 dB link margin is sufficient for the shorter link, what transmitter powers a
You are designing a PCS base station that operates at 1800 MHz. The receiver is co-located on a tower with UHF police and business radio systems that operate at 450 MHz. Since the the 4th harmonic f
Create a bandpass filter with cutoff frequencies of 100-1k, attenuate by at least 3db at desired frequency(100-1k) and at 60Hz attenuate by 10 db. Resistor, Capacitor, Inductor, and Op-amps can be u
Assume that the Fermi energy level for a particular material is 6.25eV and that the electrons in this material follow the Fermi-Dirac distribution function. Calculate the temperature at which there
An electron is bound in a one-dimensional infinite potential well with a width of 5Å. (a) Calculate the first three energy levels that the electron may occupy. (b) If the electron drops from t
a) What are the FIVE requirements for synchronizing the alternator tot he grid b) What should happen once the synchronous alternator is synchronized At that very instant, what should happen if the a
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be in
Despite the advantages to the synchronous alternator there is a downside and this has to do with keeping the load balanced on such a machine. Why is balancing the load so important to the synchronou
a) the synchronous generator has a unique ability whihc places it at the top of the heap of all machines that might be used for generation of electric power. This unique capability is what allows th
