    So, I have a high school project, and I am wondering what function generator you guys would recommend for a cyamatics rig. I already have around 200 watt amp which is connected to a subwoofer speaker. The function generator should send frequency hertz waves that go through the amplifier for amplification and then tones need to produced by the speaker.

    To buy a real function generator from 20Hz ~1Mhz or using the pc to generate the audio sound as these, and they are all free.

    Yes I can use a pc but would I need a pre amp connecting to an amp to amplify laptop signal?

    Hello,

    If you need a preamp depends on the sensitivity of the power amplifier.
    In audacity you can use the menu generate for several types of sounds to be generated.

    Doesn't the audio amplifier kind of limit the frequencies to audio? Otherwise I would also suggest ultrasonic, at least.

    20685 from Jameco Electronics. About $30.00. Built around an 8038 you can buy for less that $10.

    I have to try it in these days to make sure are they alright or not, I just thought that the old components have a long life, except the lcd display, it is really sad because they are easy damaged.

    Hi,

    Yes I looked at it, but I thought distortion might be a problem. The laptop wouldn't make an accurate enough signal, but I might be wrong. Any thoughts?

    If your talking in the 'audio' range, I'd be willing to bet you wouldn't be able to measure the amount the tones would be off accuracy. Some people use them for musical instrument tuning.
