It’s not surprising that Analog to Digital Converters (ADC’s) now employ several techniques to accomplish higher speeds and resolutions than their simpler counterparts. Enter the Delta-Sigma (Δ∑) ADC ...

A previous design had a 14 bit ADC that was sampled at a rate of 1 MHz. You would like to replace it with a 12 bit ADC, but maintain the same signal to noise ratio by oversampling. What does the ...
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 ...
No matter how many bits an analog-to-digital converter (ADC) provides, the digital output can only approximate the original signal. This approximation gives rise to ...
Vast amounts of marketing efforts are placed on touting the latest and greatest technological advancements in the realm of home audio. We are all aware of the over-inflated, and often baseless claims ...
What’s the cost of an underused hardware resource? If you spec your microcontroller to have a 10-bit analog-to-digital converter (ADC) but only require 8 bits, you’ve paid for extra performance that ...
Sensors that measure real-world variables seldom have output signals that can be directly connected to a data converter in a system. Typically, there are requirements to amplify, filter, shift offset, ...
