Coupler


Definition:

  • (19) Five frequency responses were used, two of them were defined by their response in a 2-cm3 coupler: 1) uniform coupler gain (UCG), and 2) 6 dB per rise (6 dB).
  • (20) The effect of hyperosmolarity was shown only in cells stimulated by lipolytic hormones, and the effects were still evident in the presence of high concentrations of theophylline, indicating the effect of hyperosmolarity is to facilitate hormone action on the receptor-coupler system of the adipocyte membrane.

Hook
