Originální abstrakt

Thermal noise, polarisation noise and low frequency 1/f noise are the main sources of voltage or current fluctuation in piezoceramic sensors. Noise spectral density of thermal and polarisation noise is proportional to sensor equivalent parallel resistance and decreases with increasing frequency. In the frequency range where sensor mechanical resonances appear noise spectral density may be expressed by the equation for thermal noise using equivalent series resistance value. Signal to noise ratio depends on sensor geometry and sample polarisation. Using noise generator and piezoceramic actuator, signal to noise ratio for different amplifiers and sensors was determined.
