Latest Patents

Engel's latest patents include a high-performance data tuner for video systems. This tuner is specifically designed for the recovery of a data signal injected into a video signal and subsequently transmitted over a television channel or cable. It features an IF local oscillator that is phase-locked to the input signal sync pulses, along with filters that allow only the data bandwidth to pass through. The circuit boasts a low noise figure of about 1.5 dB and a third-order intercept point of +35 dBm. Another significant patent is his software-controlled adaptive delta modulator. This delta modulator automatically adjusts the slewing rate, increasing a parameter used for the integrator in the absence of a transition in the output data. When the feedback signal overshoots the input signal, the parameter is decreased or reversed until the two signals are approximately equal, as indicated by a 50% duty cycle.
