A block diagram of a typical sampled data DSP system is shown in Figure 2-1. Prior to the actual analog-to-digital conversion, the analog signal usually passes through some sort of signal conditioning ...

An Apple patent (number 7895045) for bitrate constrained variable bitrate audio encoding has appeared at the US Patent & Trademark Office. A hybrid audio encoding technique incorporates both ABR, or ...

Sample rates for analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) continue to evolve, now reaching 5 Gsamples/s at 10-bit resolutions and 1.5 Gsamples/s at 12 bits. These ...

Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

I read your October article entitled “Digitizing audio,” and have a question on the SNR formula for digital audio. We have two different audio levels (one very ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. One of the fundamental processes involving digital signals is sampling. When sampling video and ...

Quantization is a method of reducing the size of AI models so they can be run on more modest computers. The challenge is how to do this while still retaining as much of the model quality as possible, ...
