随着自动记录设备及计算机在测试领域的应用,对脉冲信号提出了规范化要求。本文所介绍的脉冲信号自动规范化接口电路,能根据输入脉冲幅度的大小,自动选择合适的放大倍数。放大后的信号经施密特比较器和定宽定幅电路处理, With the automatic recording equipment and computer applications in the field of testing, put forward a standardized pulse signal requirements. This article describes the pulse signal automatically standardized interface circuit, according to the size of the input pulse amplitude, automatically select the appropriate magnification. The amplified signal by Schmidt comparator and fixed-width fixed-amplitude circuit processing,
