Abstract
The detecting, measuring, controlling and suppressing harmonics is extremely important. For these purposes, there are many methods in the field of harmonic analysis. However, like the methods of other fields, these methods are affected by factors such as sampling, windowing, and noise. In this study, noise sensitivities of five different transform based methods (fast Fourier transform, chirp z-transform, Hartley transform, Hilbert-Huang transform, wavelet transform) in the harmonic analysis were investigated. Performance analyzes are presented by making a comparative analysis of the related methods at different noise levels.

Abstract
Harmoniklerin tespit edilmesi, ölçülmesi, kontrol edilmesi ve bastırılması son derece önemlidir. Bu amaçlarla harmonik analizi alanında birçok yöntem mevcuttur. Ancak bu yöntemler - diğer alanlara ait yöntemler gibi - örnekleme, pencereleme, gürültü gibi faktörlerden etkilenmektedirler. Gerçekleştirilen çalışmada; harmonik analizi alanındaki yaygın beş farklı dönüşüm tabanlı yöntemin (hızlı Fourier dönüşümü, chirp z-dönüşümü, Hartley dönüşümü, Hilbert-Huang dönüşümü, dalgacık dönüşümü) gürültü duyarlılıkları incelenmiştir. Farklı gürültü seviyelerinde, ilgili yöntemlerin karşılaştırmalı analizleri yapılarak performans analizleri sunulmuştur.
