Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

We needed a handheld, battery-powered signal generator with a sine-wave output that was continuously adjustable from 100 Hz to 10 kHz. For such a wide frequency range, we selected a function-generator ...

Sometimes, there are too many choices in this world. My benchtop function generator can output a sine, square, or saw wave anywhere from 0.01 Hz up to 60 MHz? Way too many choices. At least, that’s ...

Fig 1. Two analog multipliers form a VCO with quadrature outputs, while a third multiplier provides AGC to stabilize output voltages without adding distortion. Fig 2. The oscilloscope trace of the VCO ...
