Title: Edgar Wursthorn: Innovator in Phase Detection and Tape Recording Technology

Introduction

Edgar Wursthorn is a notable inventor based in Bad Dürrheim, Germany. He holds a total of six patents, showcasing his contributions to technology, particularly in the fields of phase detection and tape recording.

Latest Patents

One of Wursthorn's latest patents is a phase detector for a phase-locked loop. This invention is designed for digital input signals, where the digital summed value for a specific number of bits equals zero. The phase detector receives sampled and digitized data, which includes a delay stage that delays the data signal by one or more sampling clock periods. The delayed and undelayed data signals are then processed in a subtraction stage, where the difference between the two input values is calculated. The processing stage assigns one of several possible values to the respective differential value, subdividing the full differential value range into sub-ranges that correspond to these possible values. The output from the subtraction stage is then supplied to a filter/control stage.

Another significant patent by Wursthorn is for a tape recorder featuring a driver circuit for a matrix head. This innovative tape recorder includes a group of write heads arranged in a matrix format, with each write head assigned to specific row and column lines. The driver circuit allows current to pass through these lines, enabling a write head to magnetize the magnetic tape permanently when the associated row and column lines have currents applied, creating reinforcing magnetic fields. The design also includes common return lines for both row and column connections.
