Wave
Wave is a sinusoidal wave which is made by a vibration of medium. A medium is the material through where a wave can travel. Wave transfer energy from one place to another. Also some wave transfer energy through a medium such a light wave transfer energy without medium. Wave point is the highest where called crest. Wave point is the lowest where called trough.
Frequency domain
Frequency domain is clearer where when we are dealing with more than one sine periodic wave.
A complete periodic wave in the time domain can be represented by one signal spike in frequency domain.
Complex periodic waveform
Complex periodic wave form is defined as up to two mixed sine wave. Which is happen various frequencies, amplitudes and phase. Various frequency, amplitude and phase can create integrated complex periodic wave
Noise waveform
Noise is unwanted form of energy. Noise is random. This unwanted energy that enters the communication medium and interference with the transmitted message. However some noise is also produced in the receiver.
Differentiate from waves:
Wave is generally a Sinusoidal wave. Simple periodic wave is also sinusoidal wave. This is transfer energy from one point to another point. Non-periodic wave is not sinusoidal wave. Its value cannot be determining any given point. Also it is not has constant basic properties of the value. But we can identify its way it means by their amplitude shape, period time. Complex periodic wave is mixed wave. This mixed wave has different frequency of the different waves. Impulse wave is not a sinusoidal wave. Which defined as spike frequency domain .noise is a unwanted energy which is disrobed and corrupt in the original signals.
Conclusion
This subject had been going through a lot of hard works. Several researches had been taken place in these assignment have dot a knowledge about this subject and we are great ful to our lecturer we have got a good understanding and it is good subject to know about the EM Wave & Telecom traffic concepts. Though I went several difficulties I was able to finish successfully with the guidance of our lecturer.
