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 ...
The ability to faithfully digitize a sine wave is asensitive test of high-resolution-ADC fidelity.This test requires a sine-wave generator withresidual distortion ...
Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...
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 ...
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 ...
