The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

1. Basic Information and Coding Theorems: entropy, Huffman Codes, Mutual Information, Channel Capacity, Shannon’s theorems; 2. Error Control Coding: Coding ...

Electronic communications began as digital technology with Samuel Morse’s invention of the telegraph in 1845. The dots and dashes of his famous code were the binary ones and zeroes of the current ...
