Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.It is an integral part of a health and nutrition assessment. Research has shown that body composition is directly related to health.io-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.
An amplifier whose output exhibits no feedback to its input side is described as 'unilateral'. The input impedance of a unilateral amplifier is independent of load, and output impedance is independent of signal source impedance. An amplifier that uses feedback to connect part of the output back to the input is a bilateral amplifier.
