Ruud M. Bolle, Jonathan H. Connell, Sharath Pankanti, Nalini's Guide to Biometrics PDF

In today’s globally hooked up international there's expanding curiosity in utilizing biometrics (personal actual attributes equivalent to fingerprints, facial photographs, voice styles, iris codes, and hand geometry) for human verification, id, and "screening" purposes. Biometrics are beautiful simply because they can't be "forgotten," should not simply stolen, and supply an instantaneous, indisputable hyperlink among a person and a transaction.

However for each input signal an extra shield drive amplifier is required. For example for a simultaneous three lead ECG recording device, three shield drives are required. For higher number of leads, analog demultiplexing reduces the required number of shield drives. For example for a 12 lead arrangement, shown in Fig. 2, eight additional op-amps are required for buffering and shield drive purposes. Fig. 9 shows the schematic of Wilson Central Terminal generation, guarding and right leg drive circuits for a 64 channel ECG amplifier [85].

An adaptive filter with a single weight has been proposed here for reducing slow wandering of baseline. A constant is used as the reference signal and the composite ECG signal with baseline wandering is the primary input. At every sample of the ECG signal, the error produced by the difference between the constant reference and the filter weight multiplied by the previous input sample (since it is a single weight filter) is used for updating the filter weight according to the least mean squares (LMS) algorithm as w[n + 1] = w[n] + 2µe[n], where e[n] is error signal, w[n] is the filter weight at nth sample and µ is the adaptation parameter.

Some part of the current may flow through the input impedance of INA if INA is AC-coupled. ACcoupled INA is desired because INA should tolerate at least ±300mV input DC offset voltage. If all components between the body and input terminals of the instrumentation amplifier are matched still CMRR of the signal conditioner module is a finite value and hence a small portion of the induced common mode signal appears as 50Hz (or 60Hz) noise in the recorded ECG. This noise disturbs the ECG, specifically P-Wave and T-Wave part of it.
