A Design and Implementation of Portable Spectrum Analyzer

A design and Implementation of Portable Spectrum Analyzer

With the progress of society signal measurement and analysis have more widely range of applications, but the spectrum analyzer was generally expensive to make it difficult for popularization and application. In this paper, a design methodology of low cost, stable reliable spectrum analyzer based on the idea of Software Defined Radio (SDR) is presented, which consists of three functional units. ...

Design and Implementation of a Kalman Filter-Based Time-Varying Harmonics Analyzer

Nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. Many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. Common techniques applied for harmonics measurement and assessment such as FFT have significant errors in presen...

Design and implementation of an image based portable ELISA analyzer using EIPA and 4PLR

Implementation of Spectrum Analyzer using GOERTZEL Algorithm

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...
