About this document
Duty Cycle Calculations for 555 Astable by Jose C. Lita Jr is a document available to read on EtoBox.
The document describes an astable multivibrator circuit that produces a square wave output. It provides formulas to calculate the period, frequency, duty cycle, and component values for the circuit. For example, with resistor R1 at 68k ohms and R2 at 680k ohms, and capacitor C1 at 1 microfarad, the circuit will output a 1 Hz square wave with 52% duty cycle. Choosing R2 much larger than R1 helps achieve a duty cycle close to 50%.
