Digital signal processing is often a mystery to many people, but the underlying principles are fairly straightforward and within the grasp of anyone with a technical background. In this feature, we’ll ...

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 ...

The market for audio applications and devices has significantly grown over the last couple of years. Applications such as smart speakers, Bluetooth speakers, smartphones, and voice-controlled ...

As we discussed at the beginning of this series, sampling has nothing to do with digitization, or quantization. A sampled signal can remain in the analog domain, though digitized signals are sampled ...
