In this case, the noise floor of the FFT would be equal to the noise spectral density of the ADC, but, the total noise power still has never changed. The same noise power is only spread across finer frequency bin widths, as seen in Figure 1. Figure 1. A Nyquist ADCs quantization nois...
This low-frequency noise characteristic is known as “1/f noise” since the noise power spectral density goes inversely with frequency (actually 1/fg). It has a -1 slope on a log plot (the noise voltage (or current) 1/√f spectral density slopes at - 1/2). The frequency at which ...
If your EMG signal has non-stationary characteristics (e.g., varying muscle activation), consider applying windowing techniques or using segments of data to compute SNR more accurately. For more complex signals, estimating the SNR using the power spectral density might yield better results, espe...

Power spectral density: As a result of the uncorrelated nature of thermal noise, power is uniformly distributed at all frequencies below some limit, i.e., it has a flat power spectral density function at sufficiently low frequencies and high temperatures. ...
