With a commendable portfolio of two patents, he has demonstrated a commitment to advancing technology, particularly in enhancing receiver performance and signal processing.

Latest Patents

Hashimoto's latest inventions include a Bandpass-limiting device for a receiver and an SSB (Single Sideband) transmitter. The bandpass-limiting device utilizes a sophisticated control mechanism for the oscillation frequencies of multiple local oscillators within intermediate-frequency circuits. It effectively limits the passband by adjusting the intermediate frequency and employs a digital signal processor to filter out noise from the detected signals. This innovative approach significantly mitigates the impact of wraparound noise, resulting in improved receiver performance.

The SSB transmitter addresses a critical issue concerning temperature variations affecting the central frequency of a bandpass filter (BPF). By implementing a microcomputer circuit that adjusts these frequencies based on real-time temperature data, Hashimoto enhances sound quality and ensures consistent extraction of sideband signals under varying conditions. This innovative solution preserves sound integrity, making it a valuable development in radio communication technology.
