一、机芯抖晃的产生机芯抖晃率是录音机机芯的主要技术指标之一。因为它的高低,直接影响到录音机整机的电声性能。机芯中磁带不规则的运动,引起记录信号的寄生调频现象称为抖晃。寄生调频的频偏对信号频率的百分比称为机芯的抖晃率。显然抖晃率是由于磁带在运行时,带速发生了瞬时波动而引起的。
First, the movement jitter Avoidance Jitter rate is one of the main technical indicators tape recorder movement. Because of its level, a direct impact on the recorder’s electro-acoustic performance. Movement of the tape irregular movement, causing the phenomenon of parasitic FM signal is called jitter. Parasitic FM frequency deviation as a percentage of the signal frequency is called the movement of the shake rate. Clearly, the dithering rate is due to the instantaneous fluctuation of the tape speed when the tape is running.
