A 'divider' is generally a digital device, so works with square wave inputs, and outputs a square wave.walters said:Frequency Divider Mixer?
Sine wave Divider Mixer?
No, it's a digital divider - you don't get analogue dividers.walters said:A 'divider' is generally a digital device, so works with square wave inputs, and outputs a square wave.
Are Flip flops analog frequency Dividers?
You can't 'divide' UP, only 'divide' DOWN.I'm trying to Divider UP and DOWN the freqency of a Sinewave how do i do this?
This sounds like the easiest way to go based on your very vague description of what you want.Nigel Goodwin said:But for a clue to most solutions, think PLL (Phase Locked Loop).
This is what you need to use, I forgot to mention you need to filter out the component you don't want. It's not exactly a divider or a multiplier, but you can get the frequencies you want with this approach. However, it is very impractical._3iMaJ said:You have to use what is called a mixer. You multiply the function that you want to change the frequency of by corresponding sine function. For example:
cos(2*pi*w*t)*cos(2*pi*b*t) = k*(cos(2*pi*(w - b)*t) + cos(2*pi*(w+b)*t))
You get the sum and difference frequencies VIA a trig identity.
k is just a constant term. Don't quote me (and with out getting a book) I think k = 1/2.
Good luck.
For the THIRD TIME - TELL US WHAT YOU ARE WANTING TO DO!.walters said:So What are the frequency divider circuits called?
I can't find any network circuits that do this because i don't know the
names of them to do a function like this?
So you have to convert Analog signals to digital signals to divide or multiple the frequency?
This is still very vague?, if you give precise details you have a chance of getting precise answers, vague details can only get vague answers. You're asking questions on how you think you can do what you want, and not on what you are actually wanting to do!.walters said:I want to take the output of my sinewave generator frequency and
divide it down or up
Sine Wave frequency 1K hz>>>Frequency divider circuit>>>500hz
Sine Wave freq 800hz>>>freq divider circuit>>>400hz
I might have to Convert the Sine wave to a Square wave to divider
or multiple the frequency
What Digital Flip flops,clocks,frequency dividers circuit is there that i can
build to do this?
You need a mixer and a filter. Its all goverened by the math I posted above.walters said:I want to take the output of my sinewave generator frequency and

It's PLL (Phase Locked Loop) not PPL.walters said:How do i use PPL circuits to do this?
I never used PPL circuits so this is all new to me can your please guide me on how to use these PPL network what i need to do to get these results and functions
