All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

Here's why I'm asking: I have a Denon AVR 3803 receiver. I like it quite a bit, except for one glaring (IMHO) omission; in order to use my Sennheiser wireless headphones, I have to run both analog and ...

A microprocessor needs to interact with the outside world. That includes communication with other microprocessors through communication protocols like I2C, SPI, and SCI etc. It also needs to ...

Confused by analog-to-digital converter specifications? Here's a primer to help you decipher them and make the right decisions for your project. Although manufacturers use common terms to describe ...

Industrial control systems can be categorized in two types: open-loop and closed-loop systems. The open-loop control system is a continuous control system that provides no feedback from its output.

In previous issues, we have discussed troubleshooting input modules. In the examples, the output modules checked out OK. But what if they don't? As with input modules, output modules can be digital or ...

An experienced circuit-design EE once clarified his view of the hierarchy of IC-vendor design support: High-performance, feature-rich ICs were good, application circuits were better, but complete ...

In a digital world, why bother with analog? Well, sometimes it can still be the right solution. Take, for instance, the analog multiplier (see figure). At its simplest, it’s a circuit that leverages ...
