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 ...

A project at Max-Planck-Institute of Quantum Optics (MPQ) and Ludwig Maximilian University of Munich (LMU) has successfully probed complex optical spectra at high resolution and very low light levels.

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 ...

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 ...
