Frequecny resolution of FFT is decided by FFT clock frequency

WebThe ADC clock is set at 1 MHz, by prescaling the system clock (16 MHz) by 16. Since every conversion takes approximately13 clocks at full scale, conversions can be achieved at a frequency of 1/13 = 0.076 MHz = 76 KHz. The sampling frequency should be significantly lower than 76 KHz to let the ADC have the time to sample the data. WebThe frequency resolution is dependent on the relationship between the FFT length and the sampling rate of the input signal. If we collect 8192 samples for the FFT then we will have: 8192 samples 2 = 4096 FFT bins If our sampling rate is 10 kHz, then the Nyquist-Shannon sampling theorem says that our signal can contain frequency content up to 5 kHz. hardwood oak floorimg memphis
