Title: The Innovations of Detlef Schwarz
Introduction
Detlef Schwarz is a notable inventor based in Hanover, Germany. He has made significant contributions to the field of radio receiver technology, holding a total of 3 patents. His work focuses on improving the performance and functionality of Phase-Locked Loop (PLL) circuits and addressing issues related to adjacent-channel interference in FM radio receivers.
Latest Patents
One of his latest patents is the "Switchable PLL circuit with constant amplification gradient." This invention enhances PLL radio receiver circuits by incorporating a phase detector, an active loop filter, and a Voltage-Controlled Oscillator (VCO). The design allows for toggling among different loop filters, which alters the loop limit frequency without significantly changing the amplification gradient across a specified frequency range.
Another significant patent is the "Adjacent channel interference detection & suppression circuit." This system addresses the challenge of intermittent adjacent-channel interference in FM radio receivers, particularly in moving vehicles. It features a dynamic bandwidth adjustment mechanism that employs signal level evaluation circuits and a variable-bandwidth filter stage. This innovation allows the system to automatically narrow the bandwidth during interference and broaden it once the interference subsides.
