[Igor] made a VU meter with LEDs using 8 LEDs and 8 comparators. This is a fast way to get one of 8 bits to indicate an input voltage, but that’s only the equivalent of a 3-bit analog to digital ...

The three most popular ADC types generally found in analog front ends are successive-approximation (a), pipelined (b), and delta-sigma (c). These block diagrams represent extremely simplified concepts ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...
