It depends on the circuit. You can indeed change a capacitor and change the frequency, but there is always at least one other component that will also do it, e.g., a resistor.What component in a simple Sawtoo Ocillator develops the output cycle ?
One method of producing a sawtooth waveform is to take a capacitor and charge it using a constant current source. This produces a linear increase in voltage across the capacitor since it is governed by the equation:What component in a simple Sawtoo Ocillator develops the output cycle ?
