Editor’s note: The first part of this two-part design idea (DI) shows how modifications to an oscillator can produce a useful and unusual pulse generator; this second and final part extends that to ...
Demodulators, directional circuits,and other electronics applicationsoften need two sine waves witha 90° difference in phase—a sine waveand its cosine wave. Engineers typicallyuse analog filters to ...
Although quite a few direct digital synthesis (DDS) ICs can generate high-frequency sine waves, their complexity excludes them from many designs. However, designers can use simple high-frequency CMOS ...
