Measurement setup for comparing the quality of biosignals recorded using two different methods. In the first method (wired transmission), the signals are recorded by the AFE of the proposed instrument and are directly digitized and depicted on the computer by a commercial instrument (Powerlab 16/35). In the second method (wireless transmission), the signals are recorded by the proposed instrument, are wirelessly transmitted to a receiver module and are depicted on the computer by the Powerlab 16/35 hardware
