Title: Innovations of John R Pacourek
Introduction
John R Pacourek is a notable inventor based in Kokomo, IN (US). He has made significant contributions to the field of electronics, particularly in the area of radio frequency technology. With a total of 2 patents, his work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is titled "Method and apparatus for tuning and aligning an FM receiver." This invention describes a method for tuning and aligning an electronically tuned FM broadcast receiver. The system compensates for the mismatch of component values between the antenna and RF amplifier tuned circuits, as well as the IF offset between the local oscillator frequency and the center frequencies of the antenna and RF resonant circuits. It develops independent tuning signals for the circuits and provides temperature compensation, allowing for alignment without the need for mechanical adjustments to inductors and/or capacitors in the tuned circuits.
Another significant patent is the "Fast locking phase locked loop frequency synthesizer." This radio apparatus features a phase locked loop that includes a phase detector with first and second inputs. The first input receives a reference frequency signal, while the second input receives a controllable frequency signal controlled by a tuning voltage. The invention also incorporates a loop filter for filtering the output of the phase detector and circuitry for decoding when a phase difference at the inputs exceeds a predetermined value. A filter bypass circuit allows for fast voltage changes of the tuning voltage, resulting in a short lock time for the phase locked loop.
