Figure bellow shows another circuit that allows adjustments in the duty cycle of the output signal. The position of the cursor of the potentiometer acts on the duty cycle with few changes in the frequency. The diodes are generaI-purpose types. With the values as shown in the figure the oscilIator wiII operate in the audio range. The Iogic functions are inverters or other gates that can be used as inverters.
