Improving FFT frequency measurement resolution by parabolic and Gaussian spectrum interpolation
Discrete spectra can be used to measure frequencies of sinusoidal signal components. Such a measurement consists of 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...
