|Abstract:||An electronic instrument capable of. measuring the period and the time of arrival of the peak of very long period nearly sinusoidal waveformswas designed. This design consists of an analog phase-locked loop device, which extracts the period in terms of a voltage and a digital counting device which establishes the voltage in a form for display on either an oscilloscope or a chart recorder. Tests show that this prototype instrument is capable of measuring periods between 10 to 300 seconds and also indicate the arrival time of the peak.|
