Title: K Virupaksha: Innovator in Speech Codec Technology

Introduction

K Virupaksha is a notable inventor based in Rockville, MD (US). He has made significant contributions to the field of speech coding technology. His innovative work has led to the development of a unique patent that enhances the efficiency of adaptive differential PCM systems.

Latest Patents

K Virupaksha holds a patent for a "Variable bit rate speech codec with backward-type prediction." This invention involves an adaptive differential PCM (ADPCM) system transmitter that utilizes three quantizers. These quantizers provide 3, 4, and 5-bit quantization at the signal sampling rate. Each quantizer generates a coded signal I(n) in the form of a bit sequence, with the number of bits varying among the quantizers. The bit rate can be adjusted by switching the codec output to selected adaptive quantizers. This innovative approach minimizes quantizing distortion during bit rate transitions, ensuring a smoother transition and improved performance.
