We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...

I needed to test a UHF linear amplifier’s ability to deliver a low distortion AM signal output. Unfortunately, the output distortion requirement was better than the distortion limits of any commercial ...

In previous installments of DSP Spreadsheet, we’ve looked at generating signals, mixing them, and filtering them. If you start trying to work with DSP, though, you’ll find a topic that always rears ...

Xitron Technologies' Model 6250 PAV phase-angle voltmeter measures AC voltage and current amplitude, phase angle, and complex impedance. It also performs frequency analysis and measures signal ...

A new phase shifter does not need clean-room facilities for fabrication, so is inexpensive to manufacture. The liquid-metal enabled phase shifting elements have a 'passive' nature, unlike the 'active' ...
