ABSTRACT:
A method of determining the difference between the actual rotational speed of the body of a guided missile and a nominal rotational speed is shown to consist of the steps of comparing a shaped output of a Hall effect cell with a shaped output of an oscillator and deriving a signal indicative of any difference between the periods of the shaped outputs.
