Triangle and square wave low frequency oscillator. Skew control at noon gives symmetrical output shapes (triangle and square). Adjusting the skew control will gradually morph the triangle into a positive or negative ramp, and will vary the pulse width of the square.   Frequency ranges from 0.01Hz (1.5 minute cycle) – 150Hz. A three position toggle switch changes between slow, medium, and fast frequency rates.
