Approximate (using a number of terms of your choice) through the three forms of Fourier series expansion the periodic signal that is depicted in the following figure
Each time,
a. Plot the approximate signal in time of three periods.
b. Compute and plot the Fourier series coefficients. Moreover,
c. Plot the line spectra.
d. Compute the approximation percentage.
CDMA is a multiple access technique to allow multiple users to share the same bandwidth, based on the orthogonality of their spreading codes. CDMA is a descendent of the direct sequence spread spectrum (DSSS) technology designed for antijam (AJ).
find the magnitude of the current density in a sample of silver for which conductivity equal to 6.17107 sm and
Sketch the following waveforms, and include the theoretical maximum and minimum values of each waveform:
If the analog signal is to be converted to a digital signal by sampling, how frequently must the meter output be sampled?
the current flowing through a circuit is it4t3a. how much charge passes through the circuit element between 0 and 2
A certain iron core has an air gap with an effective area of 2 cm×3 cm and a length lg. The applied magne to motive force is 1000 A· turns, and the reluctance of the iron is negligible. Find the flux density and the energy stored in the air gap a..
The efficiency and power factor for these conditions are 85 and 90% respectively. The combined windage, friction, and stray power losses are 1011W, the rotor conduction losses are 969W, and the stator conductor losses are 1559W.
When the scope probe is properly calibrated, it can be modeled as a 9[M Ohm] resistor in parallel with a capacitor having a capacitance l/9th that of the oscilloscope input capacitance.
A chemical plant needs a microprocessor-driven alarm system to warnof critical conditions in one of its chemical tanks. Thethank has four HIGH/LOW (1/0) switches that monitor temperature(T), pressure (P), fluid (F), and weight (W).
The forward transmittances of unity feedback tracking systemsare given below. For each, find the type number of the system, thesteady state error coefficients k0,k1, and k2 and the steady stateerrors to unit step ramp, and parabolic inputs.
Explain why AC Needs More Insulation Than DC for the Same Working Voltage Level?
