WebPhase-sensitive detection (PSD) is an established measurement technique for noisy signals. More recently, digital implementation of PSD using FPGA (Field Programmable Gate Array) or processor is becoming norm. This paper presents an FPGA-based digital PSD system, which is incorporated in a multi-channel bio-medical EIT instrument. WebThe higher the sensitivity of the metal detector, the smaller the pieces of metal it can detect. It is a clear ideal, but one that is complicated by a number of factors. We regularly refer to …
