Simplest Frequency Divider?

    If you had to divide an audio frequency (at the point it needs to be
    divided, the signal will drive an 8 ohm speaker), using discrete
    components, not an IC, what would be the simplest means? Thanks in
    advance.
     
  2. I assume you are talking about "cross-over networks". Try Googling.
     
  3. What exactly are you trying to accomplish?

    There are a lot of ways to "divide an audio frequency", but it all
    depends on what you're trying to divide. Do you just want to sound
    like Jabba or Darth? There's no simple way to do that, that I know
    of, unless you consider Digital Signal Processing simple: you'd be better
    off to get one of those Halloween voice warper mask toys and be done with
    it.

    Good Luck!

  4. Do you mean "divide", in the sense of:

    #1: splitting the power so half goes to each speaker:

    #2: divide the amplitude, or the volume

    #3: divide the frequency, for example, if you divide it by two, the
    tones drop an octave.

    #4: split the frequencies into two separate signals, such as to drive
    a woofer and tweeter?

    #5: some other meaning of "divide"?

    To divide the frequency, as in - for example, a 100 Hz audio signal in,
    50 Hz audio signal out. Thx for your time. I am also interested in how
    to multiply the frequency in the simplest possible manner using
    discrete components.

    What I've done back in my disco/boom-box days (late '70's, early
    '80's)....

    (1) Use an envelope detector to extract the amplitude variations

    (2) Then square-up the input signal and divide by 2 digitally

    (3) Use the "envelope" to modulate the amplitude of the divided-by-two
    signal.

    (4) Filter with a sharp cutoff lowpass.

    Sounds MUCH better than your classic boom-box crap which is usually
    just a regenerative distortion generator.

    Makes Sousa and even Classical music sound great!

    I have blue-prints of production designs that I can scan and post if
    there's an interest.

    Caution: This can smoke ordinary woofers ;-)
