Title: John Michael Ihle: Innovator in FSK Demodulation Technology
Introduction
John Michael Ihle is a notable inventor based in Colleyville, TX (US). He has made significant contributions to the field of communication technology, particularly in the area of frequency-shift keying (FSK) demodulation. With a total of 2 patents to his name, Ihle's work has had a lasting impact on the industry.
Latest Patents
One of Ihle's latest patents is a selective call transceiver featuring an FSK demodulator with high noise immunity. This innovative receiver is designed to receive and demodulate FSK modulated data signals, boasting improved sensitivity over substantial frequency offsets between the transmitter and receiver local oscillator. Additionally, it minimizes spurious electromagnetic radiation. The design incorporates a quadrature coupler that splits the received signal into in-phase and quadrature phase signals, which are then mixed down to baseband, filtered, and limited. An RC circuit at the output of a four flip flop demodulator averages the flip flop output signals. A voltage comparator outputs a logical 1 if the voltage at the output of the RC averaging circuit exceeds one-half the supply voltage; otherwise, it outputs a logical zero.
