Latest Patents

Fujimoto's latest patents include a Frequency Response Detection Apparatus and a Voltage/Current Conversion Circuit. The Frequency Response Detection Apparatus is designed to detect the frequency response of audio signals from left and right channels. This apparatus alternates the introduction of audio signals at a predetermined periodic rate, allowing for precise detection after dividing the signals into multiple frequency bands using band-pass filters. The system ensures that during specific intervals, the output end of the detection device is grounded, and the gain of the band-pass filters is minimized in sync with the grounding timing.

The Voltage/Current Conversion Circuit provides an output current that is proportional to an input voltage. This circuit utilizes an operational amplifier, with the input voltage applied to one of its inputs. It incorporates first and second transistors, with a feedback path connecting the collector of the first transistor back to the operational amplifier. This design allows the output from the second transistor's collector to be directly proportional to the input voltage.
