Latest Patents
Marc S. Wald holds a patent for a "Phase lock loop with tracking filter for attenuating spurious signals of a swept local oscillator." This invention focuses on a high spectral purity swept local oscillator that includes a tracking filter. The output of a swept Direct Digital Synthesis (DDS) oscillator is improved by filtering it with a band-pass filter that has an adjustable center frequency. This frequency is adjusted in real-time to track the instantaneous frequency of the DDS oscillator. The tracking process is accomplished by comparing the phase at the output of the band-pass filter to the phase at its input, using a phase comparator. A signal corresponding to the phase difference measured by the phase comparator is fed back to the frequency control input of the band-pass filter.
