A Survey on Interpolation Techniques in Digital Signal Processing

This survey examines ten research articles analyzing multiple facets of interpolation techniques, highlighting their methodologies, applications, and advancements. We categorize these techniques into linear, polynomial, spline, non-linear, and hybrid approaches, discussing their effectiveness and limitations in real-world applications. Thepaper aims to offer an in- depth analysis of the current interpolation state in DSP, identifying challengesand suggesting future research directions.
