Kindly solve the below questions:

1. Assume the AC frequency is 50 Hz. Convert these phasors to signals (remember that phasor magnitudes are RMS values of the signals)

    (a) V = 115∠90V

    (b) I = 10 + 10j A

2.  Convert these signals to phasors (remember to us RMS values for the phasor magnitude)

    (a) v(t) = 230cos (314t + 20) V
 
    (b) i(t)  = 5cos (314t + 10) A

3. Suppose the voltage across a load is v(t) and the current drawn is i(t) where 

v(t) = 230cos (314t + 20) V

i(t)  = 5cos (314t + 10) A

   (a) calculate the complex power, real power, reactive power and apparent power.

   (b) calculate the power factor and indicate if it is leading or bagging

 

A dipole antenna dimensions has been designed to operate in 65MHz.

Will the same antenna work properly if frequencies a) 130MHz b) 195MHz are used?

Your answer should include the current distribution and impedance variation along the length of the antenna and how those are affected when frequencies of 130MHz and 195MHz are introduced. Also, include sketches of radiation patterns with respect to the changes in frequencies used.

Make sure you give descriptive answer in order to achieve full marks. Use diagrams to help you with the answer.



The intensity at pixels ‘a’, ‘b’, and ‘c’ in a given image are 50, 60, and 100. Find out which of the pixels do not belong to same camera system if identical image sources are located at 10mt, 8mt, and 7.1mt respectively. Assume Gamma γ to be 1 for the given imaging systems.
