DIY SYNTH Quick Tip: Sawtooth-to-Triangle Converter

Support the channel: Working simulation on falstad: Small correction: I somewhat cut corners on the output AC coupling explanation. The reason we need to connect the 20k resistor to -12V instead of ground also has to do with the diode’s forward voltage drop (diodes only conduct if the voltage at their input is bigger than the voltage at their output). If the lowest voltage at the node after the diodes is 0V, the diodes will cut off and flatten the triangle wave’s valleys (because they’ll be blocking before the triangle can reach its lowest point, which is 0V.) Therefore by using -12V there, we can get the node to go a fair bit below 0V, allowing all of the triangle wave to be transmitted. In this new series of shorter, less basic videos, I’ll discuss smaller and/or more auxiliary circuit ideas. This time, we’re building a sawtooth-to-triangle converter that you could, for example, use with my SHAPES VCO to get another output waveform opti
