d'oh! Stupid error, sorry! I'll read what I type three times instead of twice before punching SEND from now on... Nevertheless, if you forget my erroneous 3,000,000 figure the result is the same given the manufacturer's specs. I won't be able to run the encoder at more than 1465rpm if I want the receiver to follow. So my question remains, has anybody tried dividing a quadrature signal ? regards, ----- Original Message ----- From: "Jinx" To: Sent: Saturday, June 02, 2001 9:35 PM Subject: Re: [OT] : Dividing quadrature encoder signal > > Encoder: 1024 pulses per revolution of the motor shaft and the motor > > can spin at speeds of up to 3000rpm.
