Title: Guenter Lindstedt: Innovator in Phase/Frequency Control Circuits
Introduction
Guenter Lindstedt is a notable inventor based in Freiburg, Germany. He has made significant contributions to the field of electronic control systems, particularly in phase and frequency control circuits. With a total of 3 patents to his name, Lindstedt's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Lindstedt's latest patents is a digital phase/frequency control circuit. This invention is designed to recover from modes where the oscillation of the voltage-controlled oscillator (V0) ceases. The circuit incorporates an RS flip-flop connected through two AND gates to the outputs of a phase discriminator, which generates pulses to adjust the frequency of the oscillator. Additionally, when the control circuit is out of lock, it generates a pulse using monostable multivibrators that helps manage the control voltage of the oscillator, effectively stopping unwanted modes.
Another significant patent is a remote control arrangement that utilizes pulse code modulation for transmission, similar to infrared remote control systems. This invention simplifies the design by requiring only one quartz oscillator in the receiver. The receiver measures the width of the first pulse transmitted and defines the control circuit's measure period based on that measurement. Each remote control word is also preceded and followed by a prepulse and postpulse, enhancing the reliability of the transmission.
