Recovering information from sensors
• Sensors transduce physical variables
(temperature, strain, light ...) to electrical signals
• Electronic circuits process electrical signals
for recovering the information
HOWEVER
• Sensors and circuits carry also NOISE, that is,
random fluctuations of voltage and current
• When signal is NOT much higher than noise,
the information recovered is degraded, it is
affected by significant errors
