Determine the frequency of oscillation of the circuit above, and to what value must R1 be changed to make the frequency 20 kHz. To determine the frequency of oscillation of a triangular wave ...
This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over ...
Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...
