Noise-Slide8

To convert between noise energy measurements at a certain frequency and peak-to-peak noise, the following equation can be used as an approximation for bandwidths higher than 1kHz. Filling in the measured value of 8nV per square root Hz from the previous measurement, the equation here yields an RMS noise of 800nV and a calculated peak-to-peak noise of 5.3µV. This is for the full bandwidth of up to 10kHz. Note that the 1.1µV peak-to-peak noise measured in the previous time domain plot is just for the 0.1Hz to 10Hz region.
