Title: The Innovations of Karol Siwko
Introduction
Karol Siwko is an accomplished inventor based in Batavia, NY (US). He has made significant contributions to the field of automatic frequency control systems, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
Siwko's latest patents include a "Wide Band AFC System" and a "Wide Band Automatic Frequency Control Circuit." The Wide Band AFC System detects the presence or absence of a video signal in the video channel by determining whether synchronizing pulses are present. It modifies the error voltage from the AFC amplifier when synchronizing pulses are not detected. Additionally, it features a voltage combining network that utilizes three series-connected resistors to combine a tuning voltage with the error signal for application to UHF and/or VHF tuners with varactor diodes. The Wide Band Automatic Frequency Control Circuit is designed for a signal receiver that includes a tuner, intermediate frequency (IF) amplifier, video amplifier, and sync pulse separation means. This circuit employs a discriminator coupled to the IF stage and a signal combining means to effect a specific 'pull-in' range for the tuner based on error signals from the discriminator.
