2 General Information 2.1 General Information & Safety Instructions This manual is intended to assist users in the operation of the 1-Channel Preamplifier-CFD R007 and 4-Channel Preamplifier-CFD R011. It is divided into 4 chapters. Surface Concept strongly recommends reading this manual carefully before operating the Preamplifier- CFD. -
Page 7: Cfd - Principle Of Operation
Preamplifier-CFD Manual 3 CFD - Principle of Operation 3.1 CFD - Principle of Operation The technique of the constant fraction discriminator (CFD) is based on summing the original input signal to an inverted signal. The original input signal is delayed but of full height, while the inverted signal is attenuated. -
