Title: The Innovations of Edmund Joe Tillo

Introduction

Edmund Joe Tillo is an accomplished inventor based in Belleville, MI (US). He has made significant contributions to the field of radio frequency modulation, holding a total of 3 patents. His work focuses on enhancing the performance and reliability of FM modulators, which are essential in broadcasting technology.

Latest Patents

One of Tillo's latest patents is titled "FM Modulator Output Control During Turn On." This invention provides a system and method to prevent undesired sounds during the turn-on phase of an FM modulator. The system includes an RF attenuator circuit, a delay switch circuit, an RF ramp-up circuit, and an audio ramp-up circuit. The RF attenuator circuit significantly reduces the RF signal from the FM modulator when it is initially turned on, thereby minimizing whistle caused by the RF signal interacting with the local oscillator in the radio receiver. After allowing time for the phase-locked loop (PLL) to lock onto the RF signal, the time delay switch circuit activates and charges the RF ramp-up circuit. This gradual increase of the RF signal is slower than the response time of the radio automatic gain control (AGC), preventing any popping sounds as the RF signal is provided to the radio receiver.

Another notable patent is "RF Modulator and Switch Having High Antenna Isolation." This invention features an RF modulator/switch that selectably couples a locally generated RF signal or an antenna RF signal to a broadcast radio receiver. The design includes a local RF input for the conducted RF signal and an antenna RF input for the antenna RF signal, responding to radiated RF broadcasts. A resonant network is incorporated, with a first node coupled to the antenna RF input, having a resonant frequency that corresponds to the broadcast band. The system utilizes relays to select between the local RF input and the antenna RF input, ensuring optimal performance in signal transmission.
