Most of us know about PWM DACs. They are easy to implement, cheap, and acceptable for low performance applications. The approach is to filter the HF components of the PWM signal and be left with only ...

When you need to convert a measurement signal from the digital to the analog domain, this design is a suitable solution with only two chips. Frequency-to-voltage conversion has many applications in ...

Wavelets provide new capabilities for analyzing real-time signals. This introductory article provides an overview and presents the basic mechanisms involved in wavelets. In many signal processing ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...
