Modulation & Demodulation
Modulation
Modulation - process (or result of the process) of translation the baseband message signal to bandpass (modulated carrier) signal at frequencies that are very high compared to the baseband frequencies.
Demodulation is the process of extracting the baseband message back the modulated carrier.
An information-bearing signal is non-deterministic, i.e. it changes in an unpredictable manner.
Why Carrier?
Effective radiation of EM waves requires antenna dimensions comparabl ....etc

This paper seeks to present ways to eliminate the inherent quantization noise component in digital communications, instead of conventionally making it minimal. It deals with a new concept of signaling called the Signal Code Modulation (SCM) Technique. The primary analog signal is represented by: a sample which is quantized and encoded digitally, and an analog component, which is a function of the quantization component of the digital sample. The advantages of such a system are two sided offering advantages of both analog and digital signaling. ....etc
