With a total of 11 patents to his name, Blazo's work has had a considerable impact on the industry.

Latest Patents

Among his latest patents is the invention titled "Frequency dithering for DDS spectral purity." This patent describes a frequency dither technique that reduces spurs caused by phase increment errors in a direct digital synthesizer output sinusoid. The method calculates the spurs for a desired output frequency and utilizes a pair of phase increment values that average to the desired output frequency while ensuring the spurs fall outside the phase locked loop bandwidth.

Another significant patent is the "Electrical signal jitter and wander measurement system and method." This invention operates in real-time and digitally controls the bandwidths for measurements. It includes a digital phase-lock loop (PLL) that features a phase detector, low pass filters, an analog-to-digital converter (ADC), a digital signal processor (DSP), a direct digital synthesizer (DDS), and a tracking oscillator. The system accurately measures low-frequency jitter and wander by digitally controlling the PLL filter high pass bandwidth.
