Scientists have demonstrated a technique for the recovery of weak, noise-dominated optical signals. Weak optical signals are common in many science and technology applications. However, they are ...

Even in the best designs, noise and interference sneak in to reduce the signal-to-noise ratio (SNR), obscure desired signals, and impair measurement accuracy and repeatability. Digitizing instruments ...

Electrical noise, like taxes, is always with us. Most of the time noise is small and we can ignore it, but there are some measurement circumstances where noise must be dealt with. What can be done to ...

Separating the power/ground connections used for the analog sections from those used for the digital areas will improve the isolation of the power supplies. Adding external/internal filtering should ...

When you’re hunting for a signal with your oscilloscope, the stronger it is, the better. If it’s weak, you might struggle to tease it out from other interference, or even from the noise floor itself.
