Rayleigh's theorem (also known as Beatty's theorem) states that given an irrational number there exists so that the Beatty sequences and partition the set of positive integers: each positive integer belongs to exactly one of the two sequences. Given let . We must show that every positive integer lies in one and only one of the two sequences and . We shall do so by considering the ordinal positions occupied by all the fractions and when th… Web5.) Rayleigh fading is observable when no direct line of sight with the transmitter. 6.)
