With a total of six patents to his name, Puckette's work has had a lasting impact on electronic design and communication systems.

Latest Patents

One of Puckette's latest patents involves a digital method and apparatus for reducing EMI emissions. In this innovation, a clock reference frequency is digitally derived from a base signal. The clock reference frequency is then digitally modulated by ramping it up and down around a desired frequency. This modulation occurs periodically at a prescribed modulation frequency. The result is that the electromagnetic energy of the system signals is spread over a band that is a portion of the desired clock frequency. Consequently, energy in the harmonics of the respective system signals is also spread. This energy spreading occurs over a bandwidth greater than the 120 kHz bandwidth of conventional communication receivers, which effectively reduces adverse EMI emissions.
