Hey guys,

i've been trying the whole month to build an analogic frequency to =

voltage converter, but got no good results. I can't use any black boxes =

such as LM2907, LM331, LM555, etc. I should use only opamps, resistors, =

capacitors, etc...

my input signal comes from a home-made encoder (one IR emitter spinning =

and one IR receiver fixed on the side of the motor), so that it =

generates an "impulses" in a random frequency. This frequency is what I =

want to convert to a voltage or even another kind of signal, such as a =

square or a sin waveform...

anyone got an idea?

(sorry for the bad English...)

cheers,
 Bruno
