How to use digital logic in linear mode / Sine wave synthesizer

If you need to amplify an analog signal, a digital logic gate could do the job. This video will describe how to to bias a logic inverter into linear mode. A practical example of a sine wave synthesizer using a logic inverter as an active filter will be shown. Square wave to sine converter. https://youtu.be/spKFFrYK9Cg
