alleryStart learning →Shannon channel capacity:
AC = B × log₂(1 + S/N) bits/sec — fundamental limit
BRandom
CJust BW
DJust S/N
Answer & Solution
Correct answer: A. C = B × log₂(1 + S/N) bits/sec — fundamental limit
**Shannon-Hartley theorem (1948):** maximum error-free data rate over noisy channel.
C in bits/sec, B = bandwidth (Hz), S/N = signal-to-noise ratio (linear, not dB).
Cornerstone of information theory.
Practical codes (Turbo, LDPC, Polar) approach this limit.
