What is Welch Method for Power Spectrum Analysis about?
In this paper, Power Spectral Estimation (PSE) scheme for variable data length using Rectangular, Blackman, Hanning, Bartlett and Hamming window with Welch Method. Welch method includes the periodogram having advantage of possible implementation using the Fast Fourier Transform (FFT). This method gives good resolution when optimal selection of data length samples is done. The PSE based on both Rectangular as well as Hamming window has been designed and simulated using MATLAB. It can be observed that the Rec
