sprocket pulse 时钟脉冲;[链齿脉波] 1. A pulse generated by a magnetized spot which accompanies every character recorded on magnetic tape. This pulse is used during read operations to regulate the timing of the read circuit and also to provide a count on the number of characters read from tape. 对应磁带上记录的每个字符的磁化点所产生的一种脉冲。读出时,用这个脉冲调节读出电路的同步,并对磁带上读出的字符数进行计数。 2.A pulse generated by the sprocket or driving hole in paper tape which serves as the timing pulse for reading or punching the paper tape. 由纸带上的导孔或驱动孔所产生的脉冲,用以作为读纸带或往纸带上穿孔时的定时脉冲。 |
