The wave height of a two-step integrated curve shows better proportionality to the spin number in the sample than the peak-to-peak amplitude of the signal as reported in a previous paper. However, the integration requires much time, because the base line voltage of the ESR signal fluctuates slowly and irregularly, and thus it is very difficult to compensate for the base line deviation voltage of the ESR signal. Therefore the use of a digital memory apparatus (Nicolet Digital Oscilloscope 1090A) was attempted. After the ESR signal (by JES-ME-3X) was put into the digital memory, the signal was taken out and integrated. In this case the integration time was considerably shorter, since zero-level adjustment of the base line was easier than in direct integration; moreover, the precision of the measurement increased. Another advantage of using the digital memory was that it made possible the detection and integration of a very small signal without using multiple-sweep accumulation by an electronic computer.
