What are the mathematical concepts involved in communication?
Hey what a coincidence, I just answered this same question a couple of days ago: These aren’t so much “concepts” as fields of mathematics used in communications: number theory (study of integers) for encryption/decryption, error-correcting codes, etc. trigonometry – analysis of periodic phenomena (carrier signals, modulation) complex numbers – used as a convenient way to represent trig functions using Euler’s identity; complex analysis for filter design fixed and floating point arithmetic – for digital signal processing statistics – assumptions about bit error rates, noise distributions on communications channels queuing theory – estimate throughput of statistically multiplexed channels such as switched Ethernet vector calculus – examination of electromagnetic waves used in radio communication (e.g.
