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.
I assume you are talking about "cross-over networks". Try Googling.
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! Rich
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 > Do you mean "divide", in the sense of:[snip]
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 ;-)
