The Mechanical Low Frequency Signal Reconstruction by it's Spectral Components

Abstract

This paper is a point of view of a new way of signal reconstruction through it’s spectral components. Sampling theory is analyzed from different perspectives, what means if for technical reasons the time can’t be sampled in intervals below tmin , the discrete signal is known precisely up to the harmonic ωc =π tmin . Upon reconstruction the ωc frequency is no longer relevant, the shorter the signal duration is.
