The SIM965 Analog Filter, functionally manufactured by Stanford Research Systems, is specifically designed for signal conditioning procedures wherein Besser or Butterworth filters are necessary. These filters provide a clean-step response (negligible overshoot) and linear-phase response, whereas Butterworth filters offer an outstanding pass-band flatness with some overshoot. An option of a high-pass or low-pass filtering is chosen from the front panel while frequencies are set with 3-digit resolution with a choice of 12, 24, 36, and or 48 dB/octave roll to be proved for either filter type.sim965的模拟滤波器由斯坦福研究系统功制的是专的信号理程序其中瑟或Butterworth滤波器是必的。些滤波器提供了一个干净的响应可以忽略不的冲和线性相位响应Butterworth滤波器提供了一个优秀的带平坦一些。一个或低滤波择从板率置位分率的择122436个或48分/倍程明为滤波器类型。
