Putting a buffer circuit in-between will let the oscillator ... turning the triangle wave into a sawtooth. How does that work? Well, instead of charging and discharging the timing capacitor ...
It is often used in sound synthesis. See also: Fourier Theorem, Oscillator. Compare: Pulse, Square Wave, Triangle Wave. Sawtooth wave, its description as a Fourier series, and as a line spectrum.
See: INTERFERENCE, STANDING WAVES. Successive approximations of a SAWTOOTH WAVE by addition of harmonics with amplitude inversely proportional to the harmonic number. The resultant waveform at each ...
