    Hi.
    I need an IC for multiplying tow voltage(sinosuidal and pulse)with frequencies around 3KHz.
    If anyone help me with this matter,I will be very grateful of him/her.

    Are you gating the sinusoid with a digital pulse or are you modulating the digital wave with a sine envelope?

    You might consider using an analog gate such as a CD4066.

    thank all of you,due to spending time for answering me.my perpose is generating a waveform(special one,not only a sine one,there must be some changes in the original waveform that I know how to do,but I wanted to remove some part of it by a periodic pulse).
