EXAMPLE 8.14 For the astable multivibrator using the op-amp shown in Fig. 8.67, R = 10 km2, C = 0.01 μF and R₁ = 5 k2. It is desired to make the frequency of the output square wave adjustable from 10 kHz through 100 kHz by making R₂ adjustable. Through what range of values should R₂ be made adjustable to obtain the required frequency range? C lution
