Abstract: “At the moment determining of the pulse wave main parameters using a piezo sensor is performing using the RC adjustments in the circuit. With the increasing adaptation of the virtual instrumentation it is possible to reduce the RC complexity. The purpose of this work was to determine the piezo-electric actuator transfer function according to the signal of the air pressure sensor using virtual instruments. In this works it was created a virtual piezo-electric sensor transfer function measurement model which proved that in order to change the sensor frequency amplitude we do not need to use electronics components.”
