The sources of noise in a signal chain can be either internal or external. Managing noise in the signal chain requires meticulous examination of each circuit in the chain to minimize noise where ...

It’s a counterintuitive result that you might need to add noise to an input signal to get the full benefits from oversampling in analog to digital conversion. [Paul Allen] steps us through a simple ...

Over the past decades, the high-speed analog-to-digital converter (ADC) performance metric that mattered to most has changed, albeit slowly. Primarily as a result of signal acquisition systems’ ever ...

So, I was consulting into one of our teams that was putting together a cool data acquisition subsystem. They wanted to use (OK, I admit it, I also wanted them to use) my DIY AC line filter (as written ...

The expanded availability of high-speed and very-high-speed ADCs and digital processing is making oversampling a practical architectural approach for broadband and RF systems. Semiconductor scaling ...

A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...
