How do I increase the resolution of my FFT?

The most intuitive way to increase the frequency resolution of an FFT is to increase the size while keeping the sampling frequency constant. Doing this will increase the number of frequency bins that are created, decreasing the frequency difference between each.

Does zero padding improve FFT resolution?

Zero padding enables you to obtain more accurate amplitude estimates of resolvable signal components. On the other hand, zero padding does not improve the spectral (frequency) resolution of the DFT. The resolution is determined by the number of samples and the sample rate.

What is the resolution of the FFT?

Frequency resolution is 10 Hz. The time waveform with length of 0.1 seconds is used for an FFT analysis. The spectrum values are obtained by performing FFT every 10 Hz. The spectrum cannot be obtained with the fractional frequency component values, such as 995, 1001 Hz.

How do you increase frequency resolution in spectrogram?

In order to increase the precision of the peak frequencies beyond the spectrogram resolution, an interpolation algorithm is used. This parameter determines the number of points used for interpolation.
