Duty cycle in astable multivibrator
WebCircuit Description. This is a 50% Duty Cycle Astable Multivibrator using the 555 timer IC. An approximately 50% duty cycle is achieved by discharging the timing capacitor through a voltage divider from Vcc to the discharge pin. This allows the discharging period to be equal to the charging period by finding the proper combination of Ra and Rb. WebA multivibratoris an electronic circuitused to implement a variety of simple two-state[1][2][3]devices such as relaxation oscillators, timers, latches and flip-flops. The first …
