Q4: Draw a diagram for astable multivibrator using 555 timer. Find the oscillationfrequency of the output signal and its duty cycle when the external capacitor is 0.01μF, the R1 and R2 are 10 kn and 50 kn respectively. While the decoupling capacitorequal 0.1 µF. What happened to the duty cycle when R2 become 1M?

Given Capacitance C = 0.01 μF Resistance R1 = 10 kΩ Resistance R2 = 50 kΩ Capacitance C1 = 0.1 μF
