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 ...

The most important thing to remember about both DACs and ADCs is that either the input or output is digital, and therefore the signal is quantized. That is, an N-bit word represents one of 2N possible ...

Jefferay Lawton, Senior Product Marketing Manager from Microchip’s Analog and Interface Division, introduces the first edition of ADC Aspects, a series of short discussions about the analog-to-digital ...

Basic review of how the different kinds of analog-to-ditital converters wor, with a sidebar relating them to appropriate applications. ADCs quantize time-varying analog voltages into a sequence of ...

If the input signal moves at least the analog-to-digital converter’s (ADC’s) resolution (Δ) over the time it takes to take multiple samples, the average result of these multiple signals will increase ...

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) = ...
