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 ...

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 ...

Growing demands in wideband radio and wireless communication deployments are imposing the necessity of a proper radio architecture capable of providing solid performance, more flexibility, in addition ...

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 ...

Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies around the sampling frequency, fS. When the difference signals fall into the ...

Do you keep hearing people talk about sampling rate in music? But aren’t certain what that actually is?? Well, friend, you’ve come to the right place. On a fundamental level, sampling rate is a result ...

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 ...
