How does the signal generator work the first stage of the signal generator is a vco which stands for voltage controlled oscillator this vco is made up of op amps u3a and u3b where u3a is configured as an integrator and u3b is configured as a schmitt triggerwhen an input voltage is applied to the vco via rv4 the integrator u3a integrates this constant voltage which results in the output . Building your own the aim is to build a reliable function generator that can go up to 1mhz in frequency up to 9v in amplitude and that allows you to choose between sinusoidal triangle and clock ie rectangular with 50 duty cycle signals
