intermodulação de desmoduladores de FM por PLL". 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, (1996): https://proa.ua.pt/index.php/revdeti/article/view/19902.
