Provides signal (READY output high} only when tachometer pulses from motor are within specific upper and lower limits. Also provides over speed output signal when upper limit has been exceeded. Single-action triggering eliminates instability at decision point. Article covers circuit operation in detail and gives timing diagram.-W.
