ABSTRACT:
An apparatus and method for monitoring the incoming transducer signal or synchronizing signal from an optical encoder in real time and display the degree of stability. The incoming transducer signal or optical encoder signal comprises of a certain number of voltage pulses. The number of pulses for a set period of time is measured to develop an actual frequency of voltage pulses per set unit of time. Furthermore, a representative numerical value for the time between two adjacent pulses is also developed. This time between adjacent pulses is altered by means of a look-up table to develop an average pulse frequency for that same set period of time. The average value for this period of time is then compared against the actual frequency of voltage pulses per set period of time. This comparative value can then be outputted to a display.
