Title: The Innovations of Fritz M Rothacher

Introduction

Fritz M Rothacher is an accomplished inventor based in Newport Beach, CA (US). He has made significant contributions to the field of sample rate conversion, holding 2 patents that showcase his innovative methodologies. His work has had a profound impact on the way audio signals are processed and converted.

Latest Patents

Rothacher's latest patents include "Sample rate conversion for synchronous variable rate" and "Distributed decimation sample rate conversion." The first patent extends the concept of integer ratio sample rate conversion to fractional values. This methodology allows for sample rate conversion across all synchronous rates derived from the same crystal oscillator. The implementation involves accumulating the value of N/D and selecting either M or M+1 as the sample rate ratio based on overflow conditions. The second patent discloses a system for decimating a source signal by a non-integer factor to achieve a sink signal with a different sample rate. This system first determines a decimation factor based on the ratio of the source sample rate to the sink sample rate, ultimately leading to an intermediate signal that is then converted to the desired sink signal.
