Question

Derive formulas for duty cycle and frequency in terms of and c for a 555 astable multivibrator. (test your formulas by re-solving problem 14–17.)

Answer 1

50% Duty Cycle Astable Oscillator. The 555oscillator now produces a 50% duty cycle as the timing capacitor, C1 is now charging and discharging through the same resistor, R2 rather than discharging through the timersdischarge pin 7 as before.
