In an FFT representation of converter data, the average noise floor (D) is a root-mean-square combination of all the bins within the FFT plot but excludes the input signal and signal harmonics. You ...

Figure 1 An FFT uses sampled data from an ADC. In this FFT plot, there are4096 samples that the converter acquires at a data rate of 200k samples/sec. The SNR(Point C) in this plot is a calculated ...

This FFT plot shows the test results of a SAR-ADC using coherent sampling with a data record (M) of 32,768 samples. The sampling frequency is locked to fS = 705.882 kHz, and the desired test input ...
