Analysing harmonic content of ac voltage waveformsAn a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at a frequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental, a 5th harmonic which is 10% of the fundamental and at a phase angle of 1.2 radians lagging.
(i) Write down an expression for the voltage waveform.(ii) Sketch the waveforms of the harmonic components.(iii) Determine the voltage at 20 ms.(iv) Given an ideal V = 100 V rms, what is the percentage error at 20 ms?
What are some of the possible biases and points of error that may arise in team communication systems and what are the advantages and disadvantages of a transactive memory system (TMS) in a team
Examining frequency to time domain signals, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates t..
Evaluate the TL parameters. Include the effect of the earth as ideal. Do not incorporate the effect of the shield wires.
In a typical mobile communications base station (or cell site), a radio frequency (RF) signal is amplified in the base station and then sent (over cable) to the antennas at the top of the tower.
Absorption loss of metal shielding, A plane metal shield offers an absorption loss of 30 dB at a frequency of 10 kHz to normally incident radiated emission.
Explain the following terms; (i) critical radius of insulation. (ii) economic lagging thickness.
