Hi, i want to activate a dc motor via a specific frequency between
50Hz an 1kHz.When we got this specific frequency, i want the motor run
the time this frequency is there.

Do you have any idea how i can make this kind of circuit or any web
site that can help me please?

Does it need to be exactly a certain frequency or any frequency in
a range, and if in a range what range would that be? Does it need to
cut off at a high resolution, or can you tolerate the circuit cutting
off the motor at 'about' frequency X (within how many Hz?)?
Depending on your needs, a bandpass filter driving some sort of motor
switch (what kind depends on your output) might do it. More specific
information about your output would help (voltage, amperage, frequency
or frequency range). Also more information about the frequency
resolution required of the circuit would help.

Thanks for response. the range of frequency i would like to use his
between 50 to 500 hz. the voltage range is the same as audio output on
a computer audio card between 0v to 5v I think.


thanks for the schema but the lm567 is a discontinued part. maybe
they're an alternative to this ic? or a filter can do the same? I want
to adjust between the range of 50hz to 500hz.


thanks for the help
