    pulse amplitude modulation

    dear friends


    plz i need a usufull and simple design to the circuit (pulse amplitude modulation) and i hope if anybody help me to simulate it in orcad


    appreciate your works



    thanks a lot regards

    Re: pulse amplitude modulation

    my friend could you please give me a circuit diagram without IC's . i mean with components ( op Amp - R-L-C......)



    thanks a lot

    Re: pulse amplitude modulation

    when i want to add pulse generator in ORCAD . there are many inputs i don't know what is the meaning of them whice are : V1-V2-TD-TR-TF_PW and PER ?


    so could you please give me a random valuse to these inputs

    regards

    V1 Starting voltage for pulse
    V2 Second voltage for pulse
    TD Time delay. Voltage will remain at V1 until this specified time.
    TR Rise time. Time required to reach V2 from V1 (Rise time must not equal to zero).
    TF Fall time. Time required for voltage to change from V2 to V1 (Again, fall
    time must not be equal to zero).
    PW Pulse width. Amount of time pulse remains at V2.
    PER Period of pulse. How often pulse actually repeats itself
