... • Prime distribution function π(n) is the number of primes <= n. • Prime Number Theorem: • lim n→∞ π(n) / (n/ ln n) = 1 • i.e for large n the number of primes <= n is (n/ ln n) • i.e we need to check about ln n numbers <= n for primality to find a prime that is of same length as n. • Thus step 1 of ...

... Sierpinski [6, p. 127] states that Andrew Schinzel has proven that there are an infinite number of solutions for every k-tuple in (2) . However, in the source cited, Trost [14] only appears to credit Schinzel with the proof of infinite &-tuples in (2) when k is of the form 4n or 4n + 1, where n is a ...

A Custom built UHF to VHF downconverter
... VCO shielding. It is suggested that a more affordable single channel FM demodulator be constructed as a cheaper alternative to this UHF downconveter that needs a 2m receiver. This UHF downconverter can be used as a basis and adding a 21.4MHz IF demodulator using the MC33xx or NJM33xx range of FM dem ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
