And that's exactly what it is: a RF Power Combiner simply combines (sum) different signals in a single output. In the above case, the signals are transmitted over port B and C go out through that output (A).
The body mass index (BMI) or Quetelet index is a value derived from the mass (weight) and height of an individual. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m 2, resulting from mass in kilograms and height in metres.
Body mass index (BMI) represents the relationship of height to weight, yielding a single number; the more you weigh in relation to your height, the higher your BMI. Using BMI as the measure, âobeseâ is defined as a body mass index of 30 or higher, and âoverweight as 25-29.9.MI is calculated from a person's weight and height, regardless of gender.
