Haykin received BSc (First-Class Honours) (1953); Ph.D. (1956), and DSc. (1967), degrees-all in Electrical Engineering from University of Birmingham, UK (England).He is a Fellow of the Royal Society of Canada, and a Fellow of the Institute of Electrical and Electronics Engineers for contributions to signal processing, communications theory, and electrical engineering education.

Angle modulation is a class of carrier modulation that is used in telecommunications transmission systems. The class comprises frequency modulation (FM) and phase modulation (PM), and is based on altering the frequency or the phase, respectively, of a carrier signal to encode the message signal.
For typical voice communications channels, improvements are typically 5–15 dB. FM broadcasting using wider deviation can achieve even greater improvements. Additional techniques, such as pre-emphasis of higher audio frequencies with corresponding de-emphasis in the receiver, are generally used to improve overall SNR in FM circuits.
Communication physics aims to study and explain how a communication system works. This can be applied in a hard science way via Computer Communication or in the way of how people communicate. [1] An example of communication physics is how computers can transmit and receive data through networks.
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
The current specification "Piccolo Mark IV" was still in limited use by the UK government, mainly for point-to-point military radio communications, up to the late 1990s. [4] [5] Coquelet is a similar modulation system developed by the French government for similar applications. [3]
Communications can be encoded as analogue or digital signals, which may in turn be carried by analogue or digital communication systems. Analogue signals vary continuously with respect to the information, while digital signals encode information as a set of discrete values (e.g., a set of ones and zeroes). [ 42 ]
