Source sentences:
text: When the signal is constant or periodic and the noise is random, it is possible to enhance the SNR by averaging the measurements.
text: These have to be a true power measurements that accommodate the different form factors of the variety of waveforms, i.e. sine wave for the 1 kHz tone and its harmonics, but the noise will be random and have a different form factor.
text: For this to work properly, the noise must be random and the signal must occur at the same time in each repeat.
