ADAPTIVE FILTERING FOR FSCW SIGNAL-TO-NOISE RATIO ENHANCEMENT OF SAW INTERROGATION UNITS

A digital filter that improves the signal-to-noise ratio of the response of a FSCW (Frequency Stepped Continuous Wave) scheme is presented.An improvement Cloth in signal-to-noise ratio represents an enhanced readout distance.This work considers this architecture as an interrogation unit for SAW tags with time and phase encoding.The parameters of th

During the routine postmortem inspection from carcasses and offal of slaughtered ewes in an abattoir in Isfahan (Iran), an ovine heart was discovered with a firm nodule in the myocard on palpation.In closer examination, a liquid containing cyst (1x1 cm) was recognized Recorders on left part of the heart.The cyst had thick fibrotic capsule in outer
