I HAVE BEEN ASSIGNED THE TASK OF DESIGNING THE NEXT GENERATION "TESTER"
FOR THE OPTICAL ROTARY ENCODER (THE LITTLE GUY ,ABOUT THE SIZE OF OUR 5K 
POT ).
 "I NEED INPUT"..HOW IS THIS ENCODER ENVISIONED BEING USED ?
I MEAN ,IN TERMS OF RESOLUTION.....HOW FAST WILL IT SPIN...?
THE OUTPUT RATE IS 128 PULSES/REVOLUTION PER CHANNEL (2 CHANNELS
IN QUADRATURE 90 DEGREES APART )
"BADLANDS STEERING" WAS 1:1 WITH A 58 PULSES/REVOLUTION RATE.
"WHIRLY-GIG          IS 1:1 WITH A 72   "        "        "
"RACE DRIVIN (COMPACT)" 1:1 WITH A 72   "        "        "
"ROADBLASTERS"      WAS GEARED 1:4 WITH A 36 P/R RATE....BUT THEN
                    THE STEERING WAS RESTRICTED TO 1/2 TURN,SO A
                    TOTAL OF 72 PULSES WOULD BE "SEEN" FROM
                    LOCK TO LOCK OF THE STEERING CONTROL.
....SOOO,LOOKING DOWN THE ROAD,...HOW MUCH "RESOLUTION" COULD WE
USE ,...
"GUMBALL RALLY" HAD AN ENCODER ON EACH MOTOR WHICH COULD SPIN AS FAST
AS 3600 RPM WITH 24 PULSES/ROTATION (1440 PULSES/SEC )...TO DO THE 
SAME JOB THIS NEW ENCODER WOULD NEED TO SPIN AT 675 RPM.
 IS THIS A TYPICAL APPLICATION ????
I UNDERSTAND LETA GETS INVOLVED IN THE CIRCUIT,...RUSTY,WHAT LIMITATIONS
MIGHT BE ENCOUNTERED? IS IT JUST PROCESSOR SPEED LIMITED?

IS THERE ANY REASON TO PURSUE 1,000 PULSES / MILLISECOND ?
