| 摘要 |
The present invention relates to a device for shaping a frequency analog signal, characterised in that it comprises a comparator 10 which receives from a first input 12, an input signal ENR, ENV to be shaped and which receives a reference threshold V.ANA on a second input and means S defining a variable reference threshold V.ANA, the changes in which are governed by the level of the input signal, the means defining the reference threshold S being adapted to define alternately an increasing or decreasing reference threshold V.ANA, according to whether the pulses of the input signal are positive or negative. <IMAGE>
