Want to build a signal generator? Follow these tips about constructing a high-performance DDS signal generator using an AD9851. The topics of module modification, theory of operation, and software are ...

Shannon’s sampling theorem states that a signal of frequency f can be fully captured by sampling at 2f. Modern PC sound cards support rates up to 192 kSamples/s, sufficient for signals below 96 kHz.

We usually reserve the honor of Fail of the Week for one of us – someone laboring at the bench who just couldn’t get it together, or perhaps someone who came perilously close to winning a Darwin Award ...

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 ...

If you need a very pure sine wave in the audio range, the circuit in Figure 1 can help. It is a simple deal: A sine wave with a THD of 1% coming from a function generator that goes through a trackable ...

Munich, Germany. Rohde & Schwarz has introduced a real-time control-interface software option for simulated radar scenarios based on pulse descriptor word (PDW) streaming. The radar scenario simulator ...
