伺服电路在磁带录象机中日益起着重要的作用,就象使用者要求得到优质的和复杂的性能那样,自(?)数字信号处理以来,用数字集(?)电路来实现这样的伺服系统是期望的,因为它具有计时稳定,更复杂的功能通过数字处理和较高的集成来完成。 然而,数字形式仍需要大量的模拟外部电路,象时间常数和接口电路。 在一片上包含整个系统的电路用线性兼容的双极型I~2L技术来实现。大规模集成电路应获得最好的结果。
Servo circuits are playing an increasingly important role in video tape recorders, as digital quality (?) Circuits have been implemented to achieve such servos since digital signal processing, as users demand for high quality and complex performance The system is desirable because it has stable timing and more sophisticated functions through digital processing and higher integration. However, the digital form still requires a large number of analog external circuits, like time constants and interface circuits. Circuits that include the entire system in one chip are implemented with linearly compatible bipolar I ~ 2L technology. Large scale integrated circuits should yield the best results.
