Improving FFT Frequency Measurement Resoulution by Parabolic and Gaussian Spectrum Interpolation
Discrete spectra can be used to measure frequencies of sinusoidal signal components. Such a measurement consists in digitizing a compound signal, performing windowing of the signal samples and computing their discrete magnitude spectrum, usually by means of the Fast Fourier Transform algorithm. Freq...
