Analogue Communication Lesson with Cavi.

I am not a telecommunication major, thus Analogue Communication is not part of my course. However, since I had nothing better to do am quite curious about this subject Cavi kindly decided to spend her precious time to give me a lesson on this subject. This is what I had learnt in my 2 hours lessons:

Apparently when a non-suitable filter is used, a signal would be distorted and reduced to noise such as the Hijjas signal above. Therefore, this particular 'C' filter should never be used on a Hijjas signal because once the signal is distorted, you can never recover the original signal.

On the other hand, using a suitable filter will not only preserve the shape of the signal but amplify it as well without any distortion and attenuation. Such is the example below:

One important note though, Cavi signal is an extremely sensitive signal. It is only compatible with the Ceylonese filter and nothing else. Using any other filter on a Cavi signal will only distort the signal and mess it up.

Thus, this concludes my meaningful lesson of Analogue Communication. Personally, I find this subject really tough. I will prefer Physical Electronics anytime. Even Screwhrodinger Equation doesn't look this bad...I think =)
