    [Moved] what is duty cycle of a signal

    Re: what is duty cycle of a signal then it means duty cycle is the percent of time that an entity spends in an active state as a fraction of the total time we are taking under consideration.Is this correct.if not kindly help me in understanding in this.

    Function of IC MAX 232

    i have two questions to ask about MAX 232. 1) in IC MAX 232,what is the purpose of combining the pin no (1 and 3) and pin (4 and 5) through capacitor of 1uF. 2)according to the data sheet of the IC the capacitor of 1uF attached to pin 2 could either be grounded or could be attached to Vcc.why...

    Is it possible to charge a laptop from 12V,7Ah battery using a 75W power inverter?

    @pradeep.....hmmm ok then u could recharge it but u can only charge it for one time

    Is it possible to charge a laptop from 12V,7Ah battery using a 75W power inverter?

    no, this could damag ur laptop.the charger used in the car and that of the laptop are entirely different.perhaps it can charge ur laptop but it will do more harm then to charge ur laptop

    how to solve the following equation

    ok sorry for incorrect equation here's the correct equation IF A=0 in logic expression Z= [A+EF+!BC+D][A+!D!E+!BC+!D!E],then A) Z=0 B) Z=1 C) Z=BC D) Z=BC plz solve with complete steps.
