Introduction to Communication Systems: Analog vs. Digital ExplainedThe Journey of a Signal

Amplitude & Frequency Modulation (AM & FM): We explain the core concepts of analog modulation and how information is encoded into carrier wave peaks and frequencies, including a look at their respective waveforms. • Analog vs. Digital Communication: A side-by-side comparison of these two systems, highlighting why modern technology has shifted toward digital. • Digital Modulation (ASK, FSK, PSK): A detailed look at Amplitude Shift Keying, Frequency Shift Keying, and Phase Shift Keying, including their waveform representations. • The Impact of Noise: Learn what noise is in a communication context and the various effects it has on signal integrity and data accuracy. • System Architecture: We break down the standard block diagram of a communication system, tracing the path of information from source to destination. • Radio Wave Propagation: An explanation of how signals travel across distances using ground wave, space wave, and sky wave propagation techniques. • Why Digital is Better: A summary of the key advantages of digital modulation over analog modulation, including noise immunity and security.
