Abstract
Dynamic timing indicating apparatus has comparing, zero-crossing detecting and automatic indicating apparatus. The comparing apparatus receives a first input signal and delivers an output signal in response to the input signal. The zero-crossing detection apparatus receives a second input signal which has a zero crossover portion and occurs in timed relation to the first input signal and delivers an output in response to the second input signal. The indicating apparatus automatically indicates the timed relation between the first and second input signals in response to the outputs of the comparing and zero-crossing detecting apparatus.
