Title: Norm Filiol: Innovator in Digital Demodulation Technology
Introduction
Norm Filiol is a prominent inventor based in Ottawa, Canada. He has made significant contributions to the field of digital demodulation technology, particularly in radio receivers. With a total of 2 patents to his name, Filiol's work has advanced the capabilities of complex signal processing.
Latest Patents
One of Filiol's latest patents is a complex phase-locked loop demodulator designed for low-IF and zero-IF radio receivers. This digital demodulator coherently demodulates a low-IF or zero-IF complex signal using a complex-valued phase-locked loop (CPPL). The CPPL features a numerical controlled oscillator, four multipliers, and two combiners, which provide independent phase/frequency and amplitude outputs. The CPLL demonstrates first-order PLL dynamics without a loop filter in the feedback loop to the NCO. However, a filter with one or more poles can be included in the feedback circuit to achieve second or higher-order PLL dynamics. This innovative CPLL allows for coherent demodulation of extremely low FM modulation indexes, where the incoming frequency drift may exceed the frequency deviation. Additionally, it can coherently demodulate signals that exhibit combined amplitude and phase characteristics.
