WebJul 18, 2024 · Example 2.3.1. Solve the system x ≡ 1 (mod 2) x ≡ 2 (mod 3) x ≡ 3 (mod 5). We have N = 2 ⋅ 3 ⋅ 5 = 30. Also N1 = 30 2 = 15, N2 = 30 3 = 10, and N3 = 30 5 = 6. So we have to solve now 15y1 ≡ 1 (mod 2) – a solution is y1 ≡ 1 (mod 2). In the same way, we find that y2 ≡ 1 (mod 3) and y3 ≡ 1 (mod 5). Therefore x = 1 ⋅ 15 ⋅ 1 ... In mathematics, the Chinese remainder theorem states that if one knows the remainders of the Euclidean division of an integer n by several integers, then one can determine uniquely the remainder of the division of n by the product of these integers, under the condition that the divisors are pairwise coprime (no two divisors share a common factor other than 1).

WebTheorem. Formally stated, the Chinese Remainder Theorem is as follows: Let be relatively prime to .Then each residue class mod is equal to the intersection of a unique residue class mod and a unique residue class mod , and the intersection of each residue class mod with a residue class mod is a residue class mod .. This means that if we have we can deduce …

Range aliasing occurs when reflections arrive from distances that exceed the distance between transmit pulses at a specific pulse repetition frequency (PRF).
