Shannon theorem
Did you know?
The basic mathematical model for a communication system is the following: A message W is transmitted through a noisy channel by using encoding and decoding functions. An encoder maps W into a pre-defined sequence of channel symbols of length n. In its most basic model, the channel distorts each of these symbols independently of the others. The output of the channel –the received sequence– is fed into a decoder which maps the sequence into an estima… Webb12 nov. 2024 · Frequency is probably the most important term you’ll come across if you want to understand the Nyquist-Shannon Sampling Theorem. It is the number of full cycles that the waveform achieves in 1 second. The unit for frequency is Hertz, Hz, or cycles per second. When we say “cycle” we simply mean the passing of one peak and one trough of …
