<!-- #thumb --> <p>Happy labor day. *A day set to honor those of us that work for a living, a day of rest begun way back in 1894.</p>
<p>We started the conversation yesterday about Analog to Digital Converters and wanted to discuss how they work. *There are *a number of different types of A/D converters and since this isn’t so much a class as it is a means for us to help each other gain an overview of what’s going on, I thought I’d explain the workings of a very simple A/D, then skip all the others and go deeper on the kind that might matter to any of us in high-end audio.</p>
<p>Just for reference, the basic types of A/D Converters out there include:</p>
<ul><li>Parallel ADC</li>
<li>Successive Approximation</li>
<li>Integrator based</li>
<li>Sigma Delta 1 bit</li>
</ul><p>The end game will be to understand the last of the bunch, the 1 bit A/D Converter. *It’s going to give us both DSD and PCM out and it’s the basis of what we use in the NuWave Phono Converter.</p>
<p>But first, let’s look again at what we’re trying to do. *Then we’ll get into how we’ll accomplish this. *We will start with the basis of most modern ADC’s, PCM.</p>
<p>If you’ll recall <a title="A/D converters" href="http://www.pstracks.com/pauls-posts/ad-converters/11536/">yesterday’s post</a>*I briefly reminded you that there aren’t any such thing as 1
