Modulations

How do we vary the parameters of sine waves and encode with them?
What is a carrier and what is a baseband signal?
Why is modulation so useful?
How do we encode 0s and 1s in sine waves’ parameters?
What methods for forming the digital signals are there and what are their efficiencies?
Can we reduce the bandwidth of a signal without losing any information?
What is a filter and how do we classify them?
