hello,
[first of all a big thanks to whoever has produced this website. i am doing a foundation degree in engineering and one of the modules i am studying is electrical and electronic principles. i am mechanical biased and have never studied electrical engineering. it is completely new to me, but this website has been very useful. i have read almost all of volume 1]
anyway, back to my question.
i am working on my maths assignment at the moment. it covers trigonometry and waveforms. one of the questions has left me completely puzzled. i need to explain the following statements:
1. "the bit rate for accurate digital communication is much less than the bandwidth of the channel"
2. "the shape of a digital signal is increasingly distorted as it travels down a transmission line"
i do not have a clue what a bandwidth is. we have not covered this in class and i think out tutor is expecting us to do some research (which i did, but i still cannot understand what the relationship between bandwidth and bit rate is. can anyone help?
