一、前言减小磁带记录器的抖动,是一个非常重要的问题。例如,对一个宽频偏(±40％)调频磁记录器来说,整机的信噪比主要取决于频偏和抖动: S/N≈201ogD/F[1]S/N—信噪比(dB),D—频偏(峰—峰,百分数),F—抖动(峰—峰),百分数),例如,频偏为±40％,抖动为0.8％, I. Preface Reducing the jitter of the tape recorder is a very important issue. For example, for a wideband offset (± 40%) FM magnetic recorder, the signal-to-noise ratio of the whole unit depends mainly on the frequency offset and jitter: S / N≈201ogD / F [1] S / N- dB), D-frequency deviation (peak-to-peak, percent), F-jitter (peak-to-peak) in percent), for example, a frequency deviation of ± 40%, a jitter of 0.8%
