The communications are a key factor for the social and economical progress. The technologic development and the generalised use of the communication systems in the everyday life, increase the demand for broadband systems and high transmission technologies. In this scenario new market opportunities arise as well as new regulation challenges. This article presents an overview of the Communications Sector in Portu...
The nonlinear distortion of a PLL frequency discriminator is addressed using the Volterra Series approach. The analysis, made entirely in the frequency domain, allows distortion calculations for periodic and nonperiodic sets of discrete excitation frequencies (harmonic and intermodulation distortion up to 3rd order) and random inputs. It also includes, simultaneously, the two major...
; Este trabalho visa a descrição de um método de projecto de malhas de adaptação para amplificadores de banda larga, que conduzam a um ganho de transdução constante numa banda previamente definida.
