With the use of an additional diode and a resistor, the configuration of the figure can be obtained where the output waveform is asymmetric. The relationship of values between R1 and R2 determines the degree of asymmetry, or the brand / space relationship of the multivibrator and its frequency together is given by these resistors and by C1. In this case too, the waveform obtained at the output is rectangular, asymmetrical and the frequency limits are determined by the components. The D1 diode can be of any type of general use, or switching, for the higher frequencies.
