Abstract
An amplifier intended for a signal distribution network, comprising filter means for giving a positive slope to the curve (N, Lin, K) of the amplifier gain as a function of frequency. The filter means produce a curve (N) that satisfies the formula: L(dBμV)=K*(F)3/2 in which “L” is the level of the output signal, “F” the frequency and “K” a proportionality factor.
Claims6
A signals distribution network for amplifying signals in a predetermined frequency range, comprising:
- an amplifier;
- and
- means for giving a positive slope to a curve that represents the amplifier gain of the amplifier as a function of frequency, characterized in that said means give the curve a slope which, compared with a linear slope wherein the slope regularly increases with frequency, is smaller than the linear slope in a lower region of the frequency range, and larger in an upper region of the frequency range.
A method for amplifying signals in a predetermined frequency range intended for a signals distribution network, comprising:
- amplifying signals;
- compensating for amplifier gain as a function of frequency during the amplifying step, by giving a positive slope to a curve that represents the amplifier gain as a function of frequency;
- and
- giving said curve a slope which, compared to a linear slope in which the slope regularly increases with frequency, is smaller than the linear slope in a lower region of the frequency range, and larger in an upper region of the frequency range.
