Sawtooth Signal Generator
Sawtooth signal is used in many application, such as in PMW modulator or oscilloscope sweep circuitry.
This sawtooth wave generator gives not only the sweep signal at out 1, but also a synchronization output at out 2 when the sawtooth fly back and begin sweeping. The frequency formula of this sawtooth wave signal is:
Remember that the real frequency might be slihgtly different from the formula since the components tolerance in their value. Using the formula, the frequency of this sawtooth wave signal would be around 57Hz, using the component values as shown in the schematic.
