Monostable circuits A monostable circuit produces a single pulse when triggered. The two questions about monostables you immediately need to ask are: * How can the circuit be triggered to produce an output pulse? * How is the duration, or period, of the output pulse determined? The circuit used to make a 555 timer monostable is: The trigger input is held HIGH by the 10 k? pull up resistor and is pulsed LOW when the trigger switch is pressed. The circuit is triggered sudden transition from HIGH to LOW.The trigger pulse, produced by pressing the button, must be of shorter duration than the intended output pulse. The period, ?, of the output pulse can be calculated from the equation: Remember again about compatible measurement units: resistance capacitance period F s µF s µF ms 555 as a transducer driver A transducer is a subsystem which converts energy from one form into another, where one of the forms is electrical. In an output transducer, for example,...
