    hi all.

    we have a project for the subject digital logic design. we have to make a PWM circuit which gives the user a choice to select the duty cycle.

    i have to make the part of the circuit that generates a sawtooth wave of 215 and give the user the choice to select the duty cycle from 12.5% , 25% , 32,5% , 50% , 62.5% , 75% and 87.5%...

    i have to use counters and multiplyer as told by my teacher... i am a 3rd semester student so i dont have much knowledge in the subject and dont know which ics to use...

    please help!! i need urgent reply with complete detail as i am very confused and have to meet a deadline...
