The article deals with the Goertzel algorithm, used to establish the modulus and phase of harmonic components of a signal. The advantages of the Goertzel approach over the DFT and the FFT in cases of a few harmonics of interest are highlighted, with the article providing deeper and more accurate analysis than can be found in the literature, including the memory complexity. But the main emphasis...

Spectrum analysis is very essential requirement in instrumentation and communication signal interception. Spectrum analysis is normally carried out by online or offline FFT processing. The Goertzel algorithm is a digital signal processing (DSP) technique for identifying frequency components of a signal. While the general Fast Fourier transform (FFT) algorithm computes evenly across the bandwidt...

In this paper control of Goertzel Algorithm based shunt active power filter with sliding mode controller is considered. Shunt active power filter involves harmonics mitigation due to three phase non linear loads under balanced and unbalanced load conditions. The sliding mode controller is used to regulate voltage of the capacitor used in inverter. The sliding mode controller improves the dynami...

Spectrum analysis is very essential requirement in instrumentation and communication signal interception .Spectrum analysis is normally carried out by online or offline FFT processing. But the FFT being highly mathematical intensive, is not suitable for low area and low power applications. Offline FFT processing can’t give the real time spectrum estimation which is essential in communication si...

A common method used in tuning adaptive-passive tuned vibration neutralizers is to adjust its resonance frequency to match the excitation frequency, which has the characteristic that the phase angle between its vibrating mass and its support is −90 degrees. A sliding-Goertzel algorithm is presented and demonstrated for extracting the vibration signals at the frequency of interest. The benefit o...

The Horner and Goertzel algorithms are frequently used in polynomial evaluation. Each of them can be less expensive than the other special cases. In this paper, we present a new compensated algorithm to improve accuracy by using error-free transformations. We derive forward round-off error bound for our algorithm, which implies that yields full precision polynomials not too ill-conditioned. A d...
