Title: Innovations by Inventor Abhijit A Shah

Introduction

Abhijit A Shah is a notable inventor based in Sunnyvale, California, recognized for his contributions to the field of frequency control and demodulation methods. With two patents to his name, his innovative approaches have significantly advanced technologies in communications.

Latest Patents

Abhijit A Shah has developed two recent patents that showcase his expertise. The first patent, titled “Method and apparatus for wide range automatic frequency control,” describes a sophisticated method where an oscillator receives a control signal indicating a frequency within multiple frequency bands. The oscillator then generates a tuning signal corresponding to that frequency. The system includes receive logic that analyzes input signals to derive a sequence of values, which are then compared against a predetermined pattern. If discrepancies arise, frequency control logic communicates with the oscillator to modify the tuning signal until it matches the predetermined pattern or exhausts all frequency bands.

The second patent, called “Direct demodulation method and apparatus,” presents a demodulation circuit that efficiently detects multiple zero-crossings in frequency-shift keying (FSK) signals. This innovation allows high data rate signals to be demodulated by producing additional in-phase (I) and quadrature (Q) signal pairs that are phase-shifted. By generating zero crossing signals for these pairs, the circuit can identify more zero crossings, thereby facilitating the demodulation of higher data rate modulated signals.
