1. One kind be used for determining tuner (1a, the method for the signal strength signal intensity of input 1b) may further comprise the steps:

  • Measure the amplification characteristic of tuner and the amplification characteristic of storing described tuner according to frequency input signal,During tuner operation, use the characteristic of storage to come from the signal strength signal intensity of tuner output signal calculating tuner input, and(1a, magnification ratio 1b) is so that be predetermined strength of output signal acquisition of tuner to reduce tuner by at least one control signal (7,8).
