Latest Patents

Ritter's latest patent focuses on a field telephone system designed to improve voice transmission. This system features a widely dispersed set of telephone lines, including a page line pair and a party line pair. It incorporates audio processing equipment such as telephone handsets, handset amplifiers, receiver amplifiers, and paging speaker amplifiers. The system utilizes a narrow band FM carrier system to enhance voice clarity. The FM carrier system includes a device for generating a carrier frequency signal, a modulator for modulating the carrier frequency with an audio signal, and circuitry for transmitting the modulated signal over a line pair to a receiving station. The receiving station is equipped with circuitry that extracts the audio component of the transmitted signal and processes it for delivery to a handset. A frequency mixing arrangement is employed to ensure a low distortion carrier signal, overcoming the limitations of ordinary filtering techniques.
