  1. EE 4BD4 2013/2014 Lecture 2 Noisy Measurements

  2. Conditions of Measurement • Biopotential signals are low amplitude (<1μv – 25 mv) • Biopotential signals are low bandwidth (d.c. – 15 kHz) • Body is volume conductor (specificity of signal source) • Noise is high in bandwidth of biopotential signal (60 Hz: 30 mv on skin)
