If we want to take samples of some analog waveform, as in doing analog to digital conversions at some particular conversion rate, there is an absolute lower limit to the rate of doing conversions ...

Among the most important questions radio managers and engineers soon may face is how to implement IBOC DAB technology. Radio World has asked Ibiquity Digital Radio to answer common IBOC questions in ...

A regular reader of this column would correctly surmise that the author considers audio to be a very important part of television. We are well into the digital age in television audio and video now, ...

DSOs (digital oscilloscopes) offer a great many advantages over their analog equivalents but as they say, “There’s no such thing as a free lunch.” Digital scopes sample, digitize, and store waveforms ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Primer on Nyquist and aliasing applied to the design of input filters for ADCs. Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies ...

As you have probably noticed, there’s a new trend in the smartphone industry of including “studio quality” audio chips inside modern flagship smartphones. While a 32-bit DAC (digital to analog ...

Environmental system designers are frequently asked where to position sample points for particle monitoring, whether it is conducted in a clean device (Isolator, RABS, etc.) or a pharmaceutical ...
