The exponential Fourier series coecients for a signalx(t) are: ak= { 1.57 when k=0, 0 when k is even and k doesnt equal 0, ((-1)(k-1)/2)/k when k is odd}Determine the following:(a) Plot the spectrum of the Fourier series.(b) Determine the trigonometric Fourier series coefficients for the first 6 harmonics.(c) Determine the total power of x(t) for the first 6 harmonics(d) How much of the total power of x(t) is in the DC harmonic (i.e. k=0)
A 240kW 500V 1750 r/min separately excited dc generator has an overall efiiciency of 94%. The shunt field resistance is 60 ohms and the rated current is 5A. The I^2 R loss in the armature is 0.023 pu.
For a chip area with area 2cm x 2cm in a 180nm logic technology, what is the approximate area of the same chip when ported to a 32nm logic technology.
A differential amplifier stage has collector resistors of 5.1 Kohms each. If Ic1 = 1.35 mA and Ic2 = 1.29 mA, what is the differential output voltage.

Need for radical future plans to alleviate the very real problem we are faced with in New Zealand and address this problem, by providing an answer to Transpower
A 1.2 MW wind turbine has a rotor diameter of 64 m. the turbine operates in an area with an average wind velocity of 7.5 m/s and the air density of 1.18 kg/m^3. the turbine power coefficient including the unit efficiency is 42.8 percent.
You want to download a 5 Mbit file over a 10-Mbps Rayleigh fading channel in the 1800 MHz frequency band. You are traveling at 6 km/h and use 1000-bit packets.
An ideal p-n junction diode has saturation current Is = 3e-15 A. Calculate the diode current.
An alarm is powered by 120 VAC, and the on/off state of the alarm is controlled by an EM relay. Design the interface between a computer output port and the EM relay. The dropout voltage is 3.5 V, and the coil current needs at least 100 mA. Limit t..
If a frame is damaged then in this network the receiver sends back a request for retransmission. (For simplicity, assume all these requests arrive back perfectly at the sender). What is the mean number of transmissions required to successfully tra..
