美国LeCroy公司新推出数字滤波器软件包DFP,它能在数字示波器上实现一系列的线性相位有限冲激响应(FIR)滤波器,如低通、高通、带通、带阻、余弦、余弦基部提升、高斯、用户自定义滤波器。此软件包可通过滤除无用的频率分量从而加强检查重要信号成份的能力。它具有广泛的应用领域如:通讯频道确认、调制解调器 LeCroy, USA, introduces DFP, a digital filter software package that implements a series of linear phase limited impulse response (FIR) filters on digital oscilloscopes such as lowpass, highpass, bandpass, bandstop, cosine, cosine base Boost, Gaussian, user-defined filter. This package enhances the ability to inspect important signal components by filtering out unwanted frequency components. It has a wide range of applications such as: communication channel confirmation, modem
