    Hello
    Lately I've designed a Colpitts oscillator and now I'd like to modulate ASK method. Cn anybody help me out on how to couple my oscillator to ASK modulate it?
    Thanks

    You owe us hints...

    Which two amplitudes would you like to achieve? Or, variable?

    Usually it involves shunting the input or output by some amount with an electronic switch...
